The product is applicable for the electric connection between various thermocouples and temperature-indicating instruments with index of S, R, K，N，E，J，T to improve the thermometric precision. The general PVC insulated and sheathed extension and compensating cable has the good performances such as moisture resistance, corrosiveness resistance and flame retardance. Fluoroplastic insulated and sheathed extension and compensating cable can be used in some circumstances with special requirements of high temperature resistance, acid resistance, alkali resistance, oil resistance, abrasion resistance, ageing resistance, water proof and flame resistance. Silicone rubber insulated and sheathed extension and compensating cable has good characteristics such as oil resistance, corrosiveness resistance, ageing resistance, water proof and flexibility, etc..
The product is manufactured according to GB/T4989-94, which is equivalent to IEC584-3（1989）.
