SIWO-KUL® B20 cables are required when high flexibility and high temperature conditions are present; they are mainly used in medium-voltage motors and generators for connecting stator coils to the terminal box. They are also vital elements for wind converters, transformers, solar power inverters and other MV/LV cabinets. In drives, silicone decreases copper cross-section and gives flexibility for compactness.
SIWO-KUL® B20 6.6/7.2 kV family cables are class 5 single core cables.
This product family is designed with a PET braid, SILICONE varnished providing our customers much flexibility according to their process (VPI…).
For voltage starting 6,6 kV & cross section above 16 mm², Nexans has developed a specific patented extruded semi conductive silicon layer enabling much lower partial discharge and increasing de facto the life time of our cables.
- Copper conductor tinned, flexible IEC 60228, class 5
- Tape (up 16 mm²)
- Semi-conductive layer (only for 6.6 and 13.8 kV)
- Silicone rubber insulation
- Protective synthetic yarn braiding, SILICONE varnished
The use of silicone rubber, a high grade corona resistant insulation material, gives the cable excellent dielectric strength. The braided synthetic yarn covering, which is applied directly over the insulation, gives the cable, because of its short braiding pitch and high compactness, an excellent mechanical protection by maintaining good flexibility.
Operating temperature for continuous service extends from –55°C up to 180°C.
This product family is also part of our Windlink® offer for Wind turbines
These cables are UL (Underwriters Laboratories inc.) approved for Appliance Wiring Material (AWM), following styles 3640, 3641, 3642 and 3643, CSA File No.: 036040-0-000.
SIWO-KUL® B20 cables are in compliance with EU directives on the limits of certain metals and waste as defined on ROHS (Restriction of Hazardous Substances) and WEE (Waste from Electrical and Electronic Equipment).
SIWO-KUL® B20 is REACH conform substances benzene, C10-C13).
