Cable especially for buggy ladle

Abstract

The invention discloses a cable especially for buggy ladle. The cable comprises a plurality of conductors; and wrapping layers and insulating layers are successively arranged outside the plurality of conductors. A sheath layer is arranged outside the insulating layers of the multiple conductors; a filling layer is arranged between the insulating layer and the sheath layer and includes a high-temperature glass fiber and a plurality of tensile fine steel wires for filling. Besides, a fireproof layer, a thermal insulating layer, and an armor layer are successively arranged outside the sheath layer. According to the cable, the high temperature-resistant level is high; the molten steel and slag burning and carrion resistance capability of the cable is enhanced; the fireproof insulation capability of the cable during the application is enhanced; the cable has the excellent tensile capacity during the moving and application process; and the effect that the cable can work normally in the high temperature environment can be effectively improved.

Description

technical field [0001] The invention relates to the field of special cables, in particular to special cables for ladle cars. Background technique [0002] With the progress of the times and the development of economic construction, cables can be seen everywhere. The use environment of the cable is very special and harsh, it has to bear a lot of tension and the ambient temperature is extremely high, so there are some special requirements for the cable in some special places. The ladle car is a very critical equipment in the auxiliary equipment of the converter. A large amount of molten steel and steel slag are generated during the operation of the converter. Fire and other phenomena, ordinary ladle car cables are susceptible to environmental factors during operation, poor high temperature resistance, low fire resistance, especially poor resistance to molten steel burning, coupled with the stretching of the cable car and the wear and tear of the ground , leading to different...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a special cable for ladle cars, which effectively solves the fire insulation effect during use, ensures the service life of the cable in high temperature environments, and solves the burning of molten steel and steel slag on the cable during transportation. And some problems such as ground wear, cable car stretching and short circuit
