Description

Flexible mineral insulation fireproof cable
Technical Field
The utility model belongs to the technical field of electrical equipment and specifically relates to a flexible mineral insulation fireproof cable.
Background
In recent years, with the rapid development of economy in China, people pay more attention to safety problems, and cables are indispensable as important connection media of modern electrical equipment in residential buildings, commercial buildings, industrial areas, large-scale venues, mines, subways and other places. When a fire disaster occurs, the cable is easily blown, so that power cannot be supplied to fire-fighting facilities, and even toxic and harmful gas is released, thereby further serving as a medium for spreading the fire disaster. In addition, the cable is easily torn off when the building collapses, which causes the circuit to be interrupted, and is also one of the important problems faced by the prior art. Therefore, the fire-proof performance of the cable is of great importance for site safety and timely control of dangerous situations.
