Type K PVC Insulated Thermocouple Cable
Type K is the most widely used thermocouple in Indian industry because the Chromel/Alumel pair is stable, inexpensive and covers almost every furnace, boiler and kiln zone below 1,200°C. Because the sensor is so common, K-type extension cable is the cable most often run back to panels, PLC cards and temperature transmitters.
PVC/PVC is the economical construction for runs in cooler areas: from the field junction box to the control room, along cable trays and inside panels. It is flexible, flame retardant and available in standard colour codes.
Our Type K pvc cable uses Chromel (Ni-Cr) / Alumel (Ni-Al) conductors in KX extension grade. PVC insulation, typically up to about 85–105°C. It follows the Green (+) / White (−), green sheath colour code under IEC 60584-3, with ANSI MC96.1 colours (Yellow (+) / Red (−), yellow sheath) available for export or imported instruments. Standard sizes are 7/36, 3/26, 3/28, 3/22, 1/24, 1/22, 0.5, 1, 1.5 and 2 sq mm, in single-pair or multi-pair construction.
Accuracy depends on using cable of the same type as the sensor and connecting it with the right polarity. A Type K sensor needs Type K extension or compensating cable all the way to the instrument; copper wire or cable of a different type adds an error wherever the junction is warm. Typical tolerance: KX Class 1 ±1.5°C, Class 2 ±2.5°C (IEC 60584-3).
When ordering Type K pvc cable, tell us the conductor size, number of pairs, total length, the colour standard your panel follows and the highest temperature the cable route will see. If only part of the route is hot, we can suggest a hot-zone section in a heat-resistant construction joined to a lower-cost cable for the cool run, which keeps accuracy while reducing cost.
Rewari Cable Industries manufactures this cable at our Rewari factory and supplies it in drums or cut lengths with a Material Test Certificate for each batch, covering conductor resistance, insulation resistance and spark test. Use the thermocouple cable configurator to pick size, insulation and length, or send your drawing on WhatsApp for a quote.

Frequently asked questions
What is the colour code of Type K thermocouple cable?
Under IEC 60584-3 (used in India and Europe) it is Green (+) / White (−), green sheath. Under ANSI MC96.1 it is Yellow (+) / Red (−), yellow sheath. Tell us which standard your instruments follow.
Can I use PVC thermocouple cable close to the sensor?
Only if the area stays below about 85–105°C. Near hot equipment use fiberglass or PTFE for the first section and PVC for the cool run to the panel.
Can I use J-type or copper cable with a Type K sensor?
No. Only Type K extension or compensating cable keeps the reading correct. Other cable creates an error wherever its terminals are warmer than the instrument.
Do you supply a test certificate?
Yes. Every batch ships with a Material Test Certificate covering conductor resistance, insulation resistance and spark test.
