The center component of any cable is the conductor which carry the

signal or power through that cable. For signal & power transmission

copper is most commonly used conductor.

Insulation refers to the layer of

plastic, polymer or high temperature

compound that is applied directly

over the conductor. There are variety

of insulation along with wide

temperature range from -260 ° C to

1200 ° C.

Screening is applied for magnetic and electrical protection. There are

generally two types of Screening available :

Aluminum foil Type: - Screening is done by helically applied aluminum

foil with 100 % coverage.

Mesh Braided Type:-Screening is done by Copper wire (Bare Copper,

Tinned Copper, Nickel Plated Copper, Silver Plated Copper). It is in

mesh braided form with 70 % to 95 % Coverage area.

THERMOCOUPLE CABLE

Thermocouples cables are used to measure the

temperature directly. Extension & Compensating

wires are only use to extend a thermocouple

signal from a sensor to instrument for readings.

INSTRUMENTATION SIGNAL CABLE

Instrumentation signal cables minimise

noise and signal interference, delivering

clean signals in harsh environments and

general manufacturing operations. These

cables are designed for use in

communication and instrumentation.
