Product Description

Introduction of MICN​

Mineral Insulated Heating Cables of Cu-Ni alloy sheathed series can meet the requirements of high temperature conditions and long-distance pipelines. The maximum temperature of copper-nickel alloy sheathed heating cable provided by MICH can reach a temperature up to 400℃. Conductor resistance value ranges from 4 Ω/km to 28000 Ω/km. Mineral insulated cable has excellent mechanical strength and corrosion resistance. The heating cable of series resistance provided by MICH can meet the requirements of different powers.
