5 CONNECTIVITY SOLUTIONS FROM ONE SOURCE Due to globally growing environmental respon sibility and increased prices for primary energies, photovoltaic technology is experiencing greater growth and acceptance. Generating current directly from omnipresent, powerful sunlight is a fascinating fact. Our high quality systems add an important contribution to this technical implementation. HUBER+SUHNER has developed a high performance connectivity solution for the wiring of photovoltaic plants. High reliability even under extreme conditions is standard for our products. This connectivity solution includes our high-quality, TÜV-certified RADOX solar cables, corresponding connectors and other practical accessories. Complete wiring of a solar power plant can thus be implemented with HUBER+SUHNER systems in a continuous and nonpolluting way. Assembly time and easy product handling are as important as cost efficiency. We develop customized applications based on specific requirements from our customers. We can offer integrated components from one source and customized connectivity solutions based on years of experience. The latest technologies are involved in product development in cooperation with our customers. Due to our own R&D departments and testing laboratories we are not only able to react very rapidly to market requirements and customer demands, but also to be at the forefront of engineering. Our extensive knowledge is gained from decades of material technology, high quality, and a long service life of our products. HUBER+SUHNER is certified to ISO 9002 and ISO HUBER+SUHNER

6 HIGH QUALITY FOR LONG SERVICE LIFE The electron-beam cross-linked and non-polluting RADOX solar cables are extremely robust, highly resistant against heat, cold and weather influences like UV-radiation or ozone and hydrolysis. Additionally, these cables are halogen free, flame retardant, and do not generate corrosive gases or low smoke in case of fire. Tight production tolerances and reduced outside diameters allow for assembly with our connectors resulting in water and dust-free connections. RADOX solar connectors are also equipped with outstanding mechanical properties with high weather resistance and are also halogen free. They are especially characterized by a narrow design and a high current carrying capacity due to a low electrical resistance. HUBER+SUHNER supplies completely assembled wiring systems in required lengths or raw cable and connectors with an outdoor assembly kit. All our cables fulfill the Restrictions of the use of certain Hazardous Substances (RoHS). HUBER+SUHNER 5

10 RADOX SOLAR SINGLE-CORE AND MULTI-CORE CABLES Halogen free, high temperature resistance, weatherproof and extremely robust RADOX solar cable means flexible single and multi-core cables specially designed for wiring solar plants. RADOX solar cables are extremely robust and resist high mechanical load and abrasion. High temperature resistance and excellent weatherproofing characteristics provide a long service life. Due to RADOX technology, these outstanding properties have been achieved with small cable diameters. Tight production tolerances specifically for automated processes enable easy assembly of cables. This represents a special advantage for molding, casting or soldering with no shrinking or other changes in electron-beam cross-linked material. There is no cold flow with RADOX cables which guarantees long-term, optimum tightness for connectors or transitions. In case of fire there is no occurrence of corrosive or toxic gases. Smoke production in case of fire is very low. Characteristics - Temperature range for application -40 C up to +120 C - Short circuit resistance up to +280 C - High resistance against UV, ozone and hydrolysis - Very high mechanical robustness and resistance against water, oil and chemicals - Halogen free - RADOX electron-beam crosslinked materials do not melt or flow, even at high temperatures - Compact and flexible - Multi-core cables with potential com pensation or shielding and rodent protection - Years of approved applications worldwide - TÜV approval HUBER+SUHNER 9

15 CONTACT PRINCIPLE HUBER+SUHNER solar connectors consist of a housing and contact element. Lamella contacts made of high-quality copper beryllium are considered to be core of the connectors. Special advantages include: - Contact security - Small dimensions - Vibration resistance - Corrosion resistance - High current carrying capacity - Wide temperature range - High mechanical endurance (impact resistance) - Low, constant transition resistance Without a lamella contact these advantages cannot be achieved. The lamella contact as a flexible element provides mechanical compensation between socket and pin. The lamella produces a large contact surface between the elements and guarantees a low, constant transition resistance. 14 HUBER+SUHNER

26 CURRENT CARRYING CAPACITY OF RADOX SOLAR CABLES SINGLE-CORE 1. Scope The following tables referring to RADOX cores give easy and fast support for the layout of apparatus and components. The following remarks are based on today s state of the art and practical experience as described in the standards IEC 60216, IEC and IEC The application of products will frequently vary from the theoretical values of constant ambient temperature, constant current carrying, homogeneous laying and others. That means, in practice the theoretical current carrying will differ from the real values. For a safe layout of apparatus and components it is recommended to carry out a test with the installed wire under service conditions. 2. Definitions Current load: Continuous operation: Current rating: Temperature: current passed through the cable during operation an operation with constant current whose duration is at least long enough to allow the system to reach thermal equilibrium, but may then go on indefinitely maximum permissible current under determined operating maximum permissible conductor temperature during continuous operation temperature 3. General remarks 3.1 The current carrying capacity of cables depends on: Conductor material (copper, copper aloy, aluminium, steel) Surface treatment of the conductor (plain, tinned, silver plated, nickel plated) Conductor cross-section Thermal capacity of the insulation material Ambient temperature (air/ground temperature) Installation mode (free in the air, in cable ducts, in earth) Accumulation (single core, several cores spaced, bundles) Other ambient effects (sun--radiation, UV) 3.2. The conductor cross--section has to be selected in such a way that the actual current load does not exceed the current rating, i.e. the conductor temperature does not exceed the permissible operating temperature. The determining factor is the appropriate, most unfavourable operating condition, encountered during operation over the whole length of the cable. HUBER+SUHNER 25

A possible perforation accounts for < 30 % of the total surface Closed ducts are entirely closed. Pipes belong to this category also.

RADOX R 125 for example has a life span of 20'000 h at a conductor temperature of +120 C, which is approx. 2.5 years. If it is used at another temperature, lifetime expectations are as follows: Example RADOX solar cables: 160 C 1'250 h 150 C 2'500 h 140 C 5'000 h 130 C 10'000 h 120 C 20'000 h 110 C 40'000 h 100 C 80'000 h 90 C 160'000 h 80 C 320'000 h HUBER+SUHNER 27
