Conductor
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 & types
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.

SCREENINGScreening 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.

CABLES FOR HIGH TEMPERATURE & OTHERS
CONTROL & POWER CABLE HEAT RESISTANCE CABLE
Control & Power cable up to 1.1 KV voltage grade.
Heat resistance cables with maximum 800°C temperature withstanding

LEAD WIRE OTHER SPECIAL CABLE
Lead wire or Hook up wires handle temperature -260 °C to extreme high temperature 1200 °C with insulation PVC, PTFE, FEP, PEEK, Silicon, Glass Fiber, Ceramic Fiber etc.
Network Cables
Co-axial Cable
Lance Cable
Load Cell Cable
Composite VGA Cable
SLEEVESVariety of sleeves suitable for wide temperature range with various insulation such as PTFE, FEP, Silicon, Fiber Glass, Stainless Steel wire, Polyamide & PVC.
