THE MANUFACTURING PROCESS

Berkshire Electric Cable uses multiple processes to manufacture
insulated electric wire and cable. Depending upon your requirements,
your cables will be produced using one or more of the following
processes:

EXTRUSION

We have two different extrusion capabilities:
1. Primary Extrusion
2. Jacketing
Primary Extrusion applies plastic compounds into single conductors.
Jacketing applies plastic compounds onto multiple constructions.

CABLING

Cabling consists of twisting of two or more conductors of pairs into a
cable bundle. Cabling is done on planetary and non-planetary cablers, bunchers, twinner, and cord twisters. Planitary cablers are used to avoid residual twist in the cabled conductors.

BRAIDING

The braiding process applies a shield of copper wires. Braided synthetic
or natural fiber yarns can also be applied over insulation.

TAPING

The taping process applies a shield to individual conductors or multiple conductor groups, as an EMI/RFI (electromagnetic interference/radio frequency interference) shield.

MARKING

Cable marking can be achieved by surface printing or by indent.

IRRADIAION

The irradiation process is accomplished by using Berkshire’s 1 million volt electron beam to create a highly charged stream of electrons which modify the molecular structure of the polymers used in jacketing and insulation. Irradiation causes crosslinking of the plastic molecules. The advantages obtained by crosslinking include higher temperature resistance, increased mechanical resistance, increase tensile strength, better solvent resistance, greater toughness and cut-through resistance, lower temperature brittleness, and improved solder iron deformation.
