A brief discussion on the classifications of mineral-insulated fire-resistant cables
Currently, mineral-insulated fire-resistant cables are one of the more popular product categories in the cable industry. Depending on their structural differences, fire-resistant cables are also classified differently. But before we discuss how fire-resistant cables are categorized, let’s first take a look at what exactly makes up the structure of a cable.

MOREStructure, Features, and Applications of Mineral-Insulated Fireproof Cables
Mineral-insulated fire-resistant cables, also known as magnesium oxide cables or fire-safe cables, are constructed from the mineral material magnesium oxide combined with the metallic composite copper. The magnesium oxide insulation material is tightly wrapped around a seamless, spliced copper sheath, creating a close and integral bond between the metal core and the protective jacket.

MOREControl Cable and Its Metal Shielding Standards
Control cables are suitable for industrial and mining enterprises, as well as the energy and transportation sectors, and can be used in control and protection circuits with AC rated voltages up to 450/750V. These cables feature moisture-proof, corrosion-resistant, and damage-preventive properties, making them ideal for installation in tunnels or cable trenches.
Power cables, on the other hand, are designed to transmit and distribute high-power electrical energy along the main lines of power systems. In contrast, control cables are primarily used to deliver electricity directly from distribution points within the power system to the power supply connections of various electrical equipment and appliances. Typically, power cables have rated voltages of 0.6/1kV and above, while control cables are mainly available in 450/750V configurations.
