PAGE: 3 Test Requests: R12-11-03 Report Number: R12-11-03 Introduction: ANSI C29.17 - Clause 7.1 Tests on Interfaces and Connections of End Fittings Quadri*Sil Series 300 Post Catalog Number P300046S0040 E11-10-19 The tests on interfaces and connections of end fittings were performed on samples of Quadri*Sil Series 300 line posts. The procedure employed was as defined by ANSI C29.17. The thermal-mechanical portion of the test was performed at PowerTech Labs. The insulators tested were catalog number P300046S0040. The samples were manufactured with 1800-120V silicone rubber, Chance epoxy E-CR DD fiberglass rod and Chemlok 608 coupling agent. Test Protocol: The insulators were subjected to the test protocol that follows. 7.1 Tests on interfaces and connection of end fittings 7.1.1 Test specimens Four insulators, representative of the production process and design, shall be selected. One of these shall be reserved as a reference for the power frequency voltage test in 7.1.3.3. The insulator length (metal-to-metal) will be at least 15 times the core diameter. If shorter insulators are ested, the results are valid only for insulators up to the length tested. The insulators shall be subjected to the routine mechanical test, per section 10. 7.1.2 Pre-stressing The following tests (7.1.2.1, 7.1.2.2) shall be carried out on three test insulators in the sequence indicated below. 7.1.2.1 Thermal-mechanical test The three insulators will be loaded in cantilever and subjected to the temperature cycle described in Figure 2. The load shall be selected so as to produce the same bending moment at the base of the insulator as is exerted by 50% of the SCL in normal application. Each 24 hour cycle has a minimum of 8 hours at both +50ºC and -35ºC ±5K. The 24 hour cycle shall be run twice, with the direction of the load reversed after the first cycle. The test may be interrupted for the load direction reversal and for maintenance of the test equipment for a total duration of 2 hours.
PAGE: 4 Test Requests: R12-11-03 Report Number: R12-11-03 7.1.2.2 Water immersion test The three test insulators will be immersed in boiling water for 42 continuous hours (de-ionized water with 0.1% NaCl or tap water adjusted to a conductivity of 1650 µs/cm ±50 µs/cm at 20º C - 25ºC). After the 42 hour boiling period, the insulators will remain in the vessel until the water cools to approximately 50ºC. This temperature will be maintained until the verification tests are started. 7.1.3 Verification tests The following verification tests (7.1.3.1, 7.1.3.2, 7.1.3.3) shall be completed within 48 hours following the removal of the insulators from the water. 7.1.3.1 Visual examination The housing shall be inspected visually. No cracks or crazing of the elastomeric shed or housing are permitted. 7.1.3.2 Steep-front impulse test The three test specimens will be fitted with a sharp edged electrode, consisting of a clip made of copper strip approximately 20mm wide and less than 1mm in thickness. The electrode will be firmly on the housing or sheath between the weathersheds, forming two sections of 500 mm or smaller axial length. If the test specimens have an insulating length that is less than or equal to 500mm, the voltage will be applied between the end fittings (no clip is necessary). An impulse voltage with a steepness of at least 1000 kv/µs will be applied to each test section. Each section will be stressed with 25 impulses of positive polarity and 25 impulses of negative polarity. Each impulse shall cause an external flashover of the test section. No punctures of any part of the insulator shall occur. The electrodes used to form the test sections will be removed prior to the power frequency voltage test. 7.1.3.3 Power frequency voltage test The dry power frequency flashover voltage will be determined by averaging five flashover voltages on each insulator per ANSI/IEEE 4. The flashover voltage will be reached within 1 minutes by increasing the voltage linearly from zero. The flashover voltage of the reference insulator will be determined using the same procedure. The average flashover voltage for each test insulator will be at least 90% of the flashover voltage of the reference insulator. The three test insulators and the reference insulator will be allowed to reach thermal equilibrium with the surrounding atmosphere. All four insulator will then be subjected to 80% of the reference insulator flashover voltage for 30 minutes. No puncture of any part of the insulator shall occur, and the temperature of the shank (measured immediately after the test) will not be more than 20ºC above the ambient temperature.

The insulators were manufactured with 1800-120V silicone rubber polymer, Chemlok 608 coupling agent and Aiken manufactured epoxy fiberglass rod. Test Protocol: The test protocol of the standard follows: 7.3 Housing tracking and erosion tests 7.3.1 Test Specimen. Two insulators or test specimens will be tested, in accordance with ANSI C29.11.. The specimen length will be chosen such that the leakage distance falls between 200 and 700 mm and includes at least two weathersheds. If the same elastomeric materials and manufacturing method have been previously qualified, per ANSI C29.11, this qualification section will not be repeated. 7.3.1.1 Test chamber. The test is to be performed in a test apparatus as defined in ANSI C29.11. 7.3.1.2 Test Conditions. The test is to be performed for a duration of 1000 hours as described in ANSI C29.11. 7.3.1.3 Evaluation. No tracking is allowed. No weathershed punctures are allowed. Erosion is not allowed to reach the core. The IEC method regarding flashovers was adopted from standard 62217 as a modification. If more than one flashover occurs at the initial NaCl content, the test shall be re-started at a halved value of the NaCl content. The insulators are washed by tap water and the test re-started within 8 h (interruption times shall not be counted as part of the test duration). This may be repeated until interruptions no longer occur. The application of any of the above measures shall be noted. The numbers of flashoverss and trip-outs shall be recorded and noted in the test report.
PAGE: 18 Test Requests: R12-11-03 Report Number: R12-11-03 Test Data: The samples evaluated would have been catalog number P300008S0360. The smallest insulator that can be manufactured would include 20 weathersheds. These insulators only utilized 6 weathersheds and so had one end with a normal seal, with the opposite seal filled with RTV at the end fitting. The two sample insulatorss were mounted as prescribed in the test protocol. The test was initiated on March 7 th, 2012, and concluded on April 28 th, 2012. The applied voltage was 18.62 kv.

The Agingg or Weathering Test as outlined in ANSI C29.17 clause 7.3.2, was performed using the Fluorescent UV Method (ASTM G 53). The test was performed in QUV machines using UVB-313 bulbs. Details: The test was performed on both stressed and unstressed samples of the polymer. Stressed samples were placed in tension by bending them in half and positioning them in the machine so that the maximum UV exposure occurred on the section under tensile stress. The daily exposure cycle was 16 hours of UV exposure and 8 hours of condensation. The test protocol requires a minimum of 1000 hours exposure without evidence of cracking or crazing. Conclusions: The samples were exposed for 15055 hours total time (1004 hours UV exposure). There weree no indications of degradation, cracking, fading, chalking or loss of hydrophobicity.

SUBJECT: ANSI C29.17 DATE: November 7, 2012 PAGE 26 Test Requests: R12-11-03 Report Number: R12-11-03 I. INTRODUCTION This report describes the results of flammability tests on OB polymer compound 1800-120V. This rubber compound is used for the injection molding of insulators manufactured by The Ohio Brass Company. The tests were conducted in accordance with IEC Publication 707, Methods of test for the determination of flammability of solid electrical insulating materials when exposed to an igniting source. The specific tests employed were IEC Method FV: Flame Vertical specimen. II. RESULTS Method FV: The igniting source and test units are defined in paragraphs 9.1 and 9.2 of the referenced publication. Procedure: Each specimen is to be fixed vertically by the clamp on the ring stand. The burner is placed remote from the specimen, ignited and adjusted in the vertical position to produce a blue flame 20+-2 mm high. The flame is obtained by adjusting the gas supply and the air ports of the burner until a 20+-2 mm yellow tipped blue flame is produced and then the air supply is increased until the yellow tip disappears. The height of the flame is measured again and corrected in necessary. The burner is to be placed centrally under the lower end of the test specimen and allowed to remain for 10 s. The burner is then to be withdrawn at least 150 mm away and the duration of flaming of the specimen noted. When flaming of the specimen ceases, the burner is to be immediately placed again under the specimen. After 10 s the burner is again to be withdrawn and the duration of flaming and glowing to be noted. If the specimen drips molten or flaming material during either of the flame applications, the burner may be tilted to an angle up to 45 degrees and also slightly withdrawn away from one of the 13 mm sides of the specimen during the flame application, to avoid material dripping into the tube of the burner. If the specimen drips molten or flaming material or is consumed during the test, the burner is to be hand-held, and the 10 mm distance between the bottom of the specimen and the top of the burner tube is to be maintained during the flame application. Any molten strings of the material are to be ignored and the flame is to be applied to the major portion of the specimen.
