Most wire and cable products are products with the same cross-section (cross-section) shape (ignoring errors caused by manufacturing) and long strips. This is because they are used in systems or equipment to form lines or coils The decision.

Complete process of 16 kinds of wire and cable production processes

1.Single-core installation wire

  1. Conductor → Insulation injection → Withstand voltage test → Qualified inspection → Rolled packaging → Factory shipment

  2. Conductor → Conductor stranded wire or bundle wire → Insulation injection → Withstand voltage test → Qualified inspection → Rolled packaging → Factory shipment

2.Sheath installation wire


  1. Conductor → Insulation injection → Withstand voltage test → Combined sheath injection molding → Passed inspection → Rolled packaging → Factory shipment

  2. conductor → conductor stranded wire or bundle wire → insulation injection → pressure test → injection with combined sheath → qualified inspection → rolled packaging → factory delivery

3.Power cable

  1. Conductor → Insulation injection → Withstand voltage test → Cable or steel armor → Sheath injection → Qualified inspection → Packaging into disc → Delivery

  2. conductor → conductor stranded wire → insulation injection → pressure test → cable or steel armor → sheath injection molding → qualified inspection → packed into discs → factory

4.High voltage power cable

  1. conductor → high-voltage cross-linked three-layer co-extruded insulation injection molding → withstand voltage test → cable or steel armor → sheath injection molding → qualified inspection → disk packaging → delivery

  2. conductor → conductor stranded wire → high-voltage cross-linked three-layer co-extruded insulation injection molding → withstand voltage test → cable or steel armor → sheath injection molding → qualified inspection → package into disk → delivery

5.Control cable

  1. Conductor → Insulation injection → Withstand voltage test → Cable or shielded → Sheath injection molding → Passed inspection → Packed into discs → Factory shipment

6.Magnesium oxide mineral insulated cable

(Aka: special refractory cable)

Conductor magnesium tube → filling → magnesium powder → heading → compression → drawing → continuous annealing with gas protection → drawing (repeated) → continuous annealing with gas protection (repeated) → hydraulic test → electric withstand voltage test Sheath → Sealing → Re-inspection → Packaging → Factory


Wires and cables are used to transmit electrical (magnetic) energy, information, and wire products for electromagnetic energy conversion. The wire and cable in the broad sense are also simply referred to as cables. A narrow cable refers to an insulated cable. It can be defined as: an assembly composed of the following parts; one or more insulated cores, and the coatings they may each have. The protective layer and the outer protective layer, and the cable may also have additional uninsulated conductors.
