Product Details

High Voltage Shield Cable(HVSC) Insulated Down Conductor 50mm2 For Lightning Protection
Production Description:
High Voltage Shielded Cable(HVSC) is a high integrity low impedance cable which is designed to convey lighting engergy to ground with minimal risk of "side flashing" or structure electrification. The need to reduce "side flashing" and structure electrification protects both personnel and sensitive electronic equipment from the devastating risks of a lightning strike.

The design of the HVSC incorporates carefully selected dielectric components to ensure optimum performance under high impulse condictions , this design provides a low inductance per unit length with low surge impedance. Upon the injection of lightning current through the HVSC , the voltage rise in comparison to a standard conventional down conductor such as flat copper tape is reduced by a factor of between 25 and 30.

The HVSC provides flexible installations options,whereby the cable can be installed internal to the building through air ducts,electrical cable risers, or external to the building.
