2025 Top 10 mineral insulated cable Factory in the world - Blog

Introduction to Mineral Insulated Cable

Mineral insulated cable (MIC) is a type of cable with a unique structure and excellent performance. It consists of a copper conductor, a highly compressed magnesium oxide insulation layer, and a copper sheath. This combination gives mineral insulated cables several outstanding features.

Firstly, they have excellent fire - resistance. The magnesium oxide insulation can withstand extremely high temperatures, and the cable can continue to operate for a long time in a fire environment, providing reliable power supply for emergency equipment such as fire - fighting systems, elevators, and emergency lighting. Secondly, MICs have high mechanical strength. The copper sheath provides good protection against external mechanical damage, making them suitable for use in harsh industrial and outdoor environments. Additionally, they have low smoke and zero halogen characteristics, which is beneficial for reducing environmental pollution and protecting human health in case of a fire. Moreover, mineral insulated cables have excellent electrical performance, with low impedance and high current - carrying capacity.
