Easy-On II Terminations

Transcription

1 Features Class 1 (outdoor) termination as defined in IEEE 48 standard. For use on all extruded dielectric cables, concentric neutral, metal tape shielded or wire shielded cables without need for additional kits or tapes. The termination ground (or neutral) connection has the same ampacity as the cable shield (neutral system). Sizes are available for all shielded cables in voltage classes from 15kV through 35kV. Conductor sizes through 1000 kcmil aluminum and copper cables. Porcelain insulator provides maximum resistance to moisture, industrial pollution and seacoast pollution. Porcelain is the most reliable insulator for use where insulator dryband arcing may occur. The G&W spring loaded elastomer stress control system is the most reliable method to provide continuous mechanical force to the elastomer, thereby compensating for elastomer permanent set. The resulting dielectric interfaces have high dielectric strength, prevent ingress of moisture and accommodate the thermal expansion and contraction of the cable. The electric stress control cone is a factory made soft elastomer which seals the cable shield against environmental moisture. All of the termination interior elastomer dielectric parts are factory assembled within the porcelain termination housing. Termination field assembly is as easy as pulling the two pins releasing the elastomer compression spring. No tapes, tubes, nuts or bolts. No pushing or pulling or shrinking to fit. The Easy-On II terminations E5200, E5202 and E5203 are light enough to hang from a fuse cutout. Options for external connection to the overhead system include: pin type, 6 inch copper wire lead, eyebolt, in-line sleeve, aerial, flat bus, and spade. Galvanized steel mounting brackets are available. Page 1

3 s All Easy-On II terminations require a connector. They not only make the connection to the shielded underground cable, but they also are a part of the sealing system. Aluminum connectors are not recommended in corrosive environments or when a copper aerial drop wire is used. All compression connectors along with the applicable aerial connections (parallel groove, eyebolt, aerial and flat pad) meet all industry standards such as EEI TD-160 and ANSI/NEMA CC All the aluminum connectors are tin plated. The aerial connections are either tin plated aluminum or copper alloy. The following are the connectors used on the Easy-On II termination.

5 Ordering Information The Easy-On termination is available in two size series for each voltage class, 15 through 34.5kV. The first is the E5200 series which uses small diameter porcelains for conductor sizes through 250 kcmil. The second is the E5260 series which uses large diameter porcelains for conductor sizes through 1000 kcmil. Fill the blanks in the catalog number with the proper codes for voltage, conductor, connector and mounting or grounding option. Page 5
