High Temperature Wire Insulation Types

Fibreglass insulated and served thermocouple.

High temperature wire insulation types.

For example mgt 1000 high temp wire and cable are used with. High temperature wire is often defined as a wire with a temperature rating of 125 c or higher although high temperature can also refer to temperature ratings as low as 90 c. The entire cable is wrapped in a layer of fiberglass fabric and mica tape and then covered. Nextel 440 insulation has the highest temperature rating to 1375c 2500f silica insulation is a high purity sio2 99 ceramic yarn that offers high temperature protection up to 2000 f at an economical price.

Galaxy can supply various types of high temperature cables and wires both stock and custom in various awg sizes voltage ratings compounds shielding constructions and conductor counts. Fibreglass insulated thermocouple wire is low cost high temperature wire. Allied wire cable is a custom cable manufacturer offering custom made cable solutions for challenging applications where stock cable just won t do. The glass braid serves as a flexible insulator for the thermocouple conductors which are then impregnated with a heat and moisture resisting finish thereby promoting fibre bonding reducing fraying and providing ansi coding specifications for pigmentation and calibration.

This is one of our series of articles delving into component and material options for custom cable. Tpc has designed a specialized family of wire and cable products that can take the heat. It has a layer of fiberglass fabric and mica tape around each wire. These products commonly consist of a conductor usually annealed tinned copper copper plated or nickel coated copper and insulation.

Bryne mica high temperature wire 60 450 degree c stranded nickel plated copper wire insulation by mica and fiberglass used in harsh environments awg14 10ft 4 8 out of 5 stars 61 17 88 17. All of these high temperature cables can withstand applications in continuous heat extreme heat or flash heat. High temperature wire including thermocouple wire is stocked since many internal and external wiring applications are used in environments exceeding 150 c and even up to 200 c making it an excellent heat resistant wire we carry high temperature wire in a wide variety of materials and configurations to suit every application. Use unshielded cable in applications where signal interference is not a concern.

High temperature cables can either be single conductor or multiconductor. The wires are silver or nickel plated for corrosion resistance. Insulation is braided over each wire or leg then a final jacket of the same insulation is braided over the pair of wires. The insulation on this cable withstands high heat applications such as ovens and furnaces.
