Frequent High Temp Questions:


High-temperature oven wire &  High-Temp wire for stoves.

The application for high temp wire that we get calls about most often is high-temperature oven wire. High-Temp oven wire is used for the wiring of electric and gas range ovens, as well as quite a lot of food warming equipment applications.  Conversely, the heating element presents a unique environment for wire and cable, because of the massive amount of heat that the products are subjected to. Typically high-temp wire for stoves and high-temperature oven wire we sell the most is TGGT wire.





High Temp Wire Insulation.

Both Standard, and High-Temperature electrical wires are usually covered with insulating materials, such as plastic, rubber-like polymers, or varnish. Insulating and jacketing of wires and cables nowadays, is done by passing them through an extruder. Formerly, materials used for insulation included treated cloth or paper and various oil-based products. Since the mid-1960s, plastic and polymers exhibiting properties similar to rubber have predominated. The insulation in our high-temperature cables is diverse because we produce or supply everything from PTFE Tape and Mica Tape to Fiberglass. Additionally, we also provide Ceramic Braids on High-Temperature Wire.




High-Temperature Appliance Wire.

High-Temperature appliance wire, or “high temp” appliance wire, is primarily used in lighting fixtures, heating elements, motor leads. It is also used in internal wiring appliances. Furthermore, the intended purpose of high-temperature appliance wire is for internal wiring of appliances and fixtures. It’s also used as motor leads, transformers, or other electrical equipment where hazardous and high temperatures are prevalent.
