3 core Winding Wire

For trouble free working, the connecting cables for submersible pumps motors are just as important as winding wires. JSB 3 core flat cables are manufacturer keeping in mind severe & difficult conditions in which they are required to operate.

Conductors :
The conductors, drawn from bright electrolyte grade copper, are annealed and bunched together.

Insulation :
Bunched conductors are insulated with specially formulated, in-house developed PVC compound with high insulation resistance values. The insulation process is carried out on modern high speed extrusion lines with high accuracy, ensuring consistency in performance.

Sheath :
The insulated core are laid up to form the core assembly. The outer sheath of the cable is made from a special grade of abrasion resistant to PVC compound impervious to water, grease, oil etc. This sheathing facilitate not only ease in stripping but also to withstand mechanical abrasion while in use.
