LECTROTECH - Earth Cable - KWENA & COMPOSITE

KWENA conductor cable is a composite stranded cable made up of tinned copper wires and galvanised steel wires that are braided-interwoven to form the cable.

KWENAcan be used as earth bonding cable or jumper bonds where earth tails are above
ground, visible and open to easy theft. The complex braided and interwoven wires of steel
and copper make it very difficult to separate and is unattractive and uneconomical to copper thieves and scrap dealers.

KWENA is available in "bare" or "insulated" in black or clear.

KWENA has been tested by the SABS and Gerotek Test Facilities for electrical properties.

COMPOSITE conductor cable is a composite stranded cable made up of tinned copper
wires and galvanised steel wires that are rope layered to form the cable.
COMPOSITE applications and benefits are the same as for Kwena.
COMPOSITE is available in “bare” or “insulated” in black or clear.

KWENA and COMPOSITE conductors can be welded using LECTROWELD exothermic copper process for joining of cables. LECTROWELD can be used for joining both of these cables to Copper conductors and Steel structures.

The LECTROWELD process generates high temperatures that melt the wires, resulting in a fused joint. This high temperature will cause some melting of the tin and galvanising of the wire strands.

To prevent corrosion and or any galvanic reaction in wet or buried Kwena cable, the joint MUST be properly sealed.

After welding the joint must be Denso Paste/Denso Tape wrapped. Alternatively a bitumen must be "worked" into the cable strands whilst the joint is still hot. Protective covering of the surface strands of the cable only is not sufficient.
