Description

Cable is introduced

Mineral insulated cable (copper core copper sheath magnesium oxide insulated cable) is referred to as fireproof cable, which is called Ml cable abroad. This cable was first developed and patented by the Swiss in 1895, and was first transformed into large-scale production by France in 1934. The emergence of mineral insulated cables is an innovation of traditional cables, especially in some important places and key electrical circuits, leaving plastic cables out of sight. Because the United Kingdom, the United States, Italy, Australia, the former Soviet union and other industrial developed countries began to produce mineral insulation cables. China began to develop this product by Shanghai cable research institute in 1968. Due to the particularity of materials and structure, this product has the electrical, mechanical, environmental and environmental performance that traditional plastic cable cannot match. With the practical application of this product, mineral insulated cable has been more and more recognized by people and has been widely used in industrial and mining enterprises and civil construction.
