Features:
1) Utilizing an inner water-passing technique, our single-conductor water-cooled cable offers a rapid water-cooling effect, low cost,    long service life for a wide range of applications.
2) We produce the cables in 1.5m - 3.5m lengths with sections of 150mm or 200mm.
3) Meanwhile, we manufacture other special dimension and type of cable under requirement. 

Secondary cables for portable Spot Welding Machine

1.This specification consult to JIS C 9318

2.Ours secondary cable mainly include Kickless cable and single conductor cable.

1) Kickless cable: A low-reactance water cooled flexible cable composed of 2 separate conductors insulated mutually and braided into a single hose.

2) Single conductor cable: A water cooled flexible,in which each of go-and-return path conductors is braided into a hose,usually making a set. 

3.Specifiction
