Problems solved by technology

At present, the problem that the control wire core is easy to break and the service life is short in the rubber-sheathed flexible cable of the shearer that is used for the shearer is a key factor restricting the production efficiency of the shearer.
During the operation of the cable, due to various mechanical stresses such as frequent bending and stretching, it is easy to cause the breakage of the control wire core. Once the control wire core is broken, it will lose the monitoring and protection function and cause the equipment to stop running, seriously affecting the user. use, causing great losses to users

Abstract

The invention discloses a bending-resistant shearer cable, which comprises three power cable cores, a ground wire core, a control wire core and a filling layer; the three power cable cores, the ground wire core and the control wire core are arranged in the filling layer; The outer cover of the filling layer is provided with a CPP tightening tape layer; the outside of the CPP tightening tape layer is successively provided with an oxygen barrier layer, a heat insulation layer, a steel belt layer, a non-magnetic barbed steel wire rodent-proof layer and an outer protective layer; The power cable core includes five types of tinned copper conductor bundles, bundled conductor strands are twisted in the same direction, and the five types of tinned copper conductors are sequentially provided with an isolation tape layer, EPDM rubber insulation layer and semi-conductive shielding Floor. The invention is favorable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a bending-resistant shearer cable. Background technique [0002] As China's economic growth requires energy, it shows the importance of coal in China's energy structure and accelerates the development of the coal mining industry. Therefore, it is imminent to speed up the technological innovation and structural adjustment of the coal mine equipment manufacturing industry. At present, the rubber-sheathed soft cable of the shearer matched with the shearer is easy to break the core and has a short service life, which is a key factor restricting the production efficiency of the shearer. During the operation of the cable, due to various mechanical stresses such as frequent bending and stretching, it is easy to cause the breakage of the control wire core. Once the control wire core is broken, it will lose the monitoring protection function and cause the equipment to stop running, seriou...
