COMPENSATING CABLES

COMPENSATING CABLES

KERONE as leader in heating solutions we manufacture wide range of compensating cables with various type of insulations and protections for protecting cables from the high temperature, corrosion, moisture. The compensating cables are essential for accurate measurement of temperature at remote measurement points; they serve up as extension leads from the thermocouple sensor to the measuring instrument hence also known as Thermocouple Extension Wire. Compensating cables are built with high quality metallic materials having properties similar to that of thermocouple in operation. They are used to avoid electrical interference in precision control system.

PVC to PVC Code 'A'

The individual bare wires are extruded with colour coated polyvinyl. Both the conductors are kept in parallel and covered with PVC. They are best suited for the temperature range of 20 to 200 degree Celsius and can withstand moisture, alkalies, oil and acids. They are good dielectric, mechanically strong and economical.

PVC to PVC Plus Overall Asbestos Code 'B'

The individual conductors are PVC coated, kept together and sheathed in PVC. Finally they are coated with asbestos. The advantages are similar to that of code 'A' and besides which they are able to withstand electrical short circuits when contacted with hot surface.

Teflon to Teflon Code 'C'

The conductors are Teflon coated individually as well as when placed together. They can withstand moisture, acids, vapours and the temperature of 250°C.

Standard Wire Gauges

Standard wires are supplied with flexible 3/22 SWG conductors. The specific requirements can have the following conductors - 1. Solid Conductor - 14, 16, 18, 20 & 22 SWG. 2. Flexible Conductors - 3/20, 3/22, 7/22, 7/30, 14/30 or 24/30 SWG.

Fibreglass to Fibreglass Code 'D'

The conductors are covered with impregnated fibreglass individually and again in grouping which is finally impregnated in varnish. The impregnations helps in increasing the resistance to abrasion and moisture but are permanently destroyed above 200°C.

Asbestos to Asbestos Code 'E'

The conductors are covered with felted asbestos, placed together and overall covered with asbestos. They can withstand a continuous temperature of up to 500°C. Metal Covering Code 'F'

The metallic covering increases the resistance of the standard thermocouple extension wire against abrasion, mechanical damage and higher tensile strength. They comprise of tinned copper wires or galvanized steel wires in general. The specific requirement can be provided with Stainless steel metallic covering.
