Crosslinked polyethylene insulated halogen-free low-smoke flame-retardant polyolefin sheath power cable

Abstract

The invention discloses a cross-linked polyethylene insulated halogen-free low-smoke flame-retardant polyolefin sheath power cable which comprises a cable body. The cable body comprises a cable core body, a sheath, a flame-retardant layer, a lining layer, a shielding layer, a halogen-free wrapping layer and a flame-retardant filling rope. According to the crosslinked polyethylene insulated halogen-free low-smoke flame-retardant polyolefin sheath power cable, an output shaft of a servo motor II rotates to drive a polishing wheel to rotate, a linear motor II on the right side of a fixed frame IIslides on the surface of a linear slideway II to drive a mounting frame to shift, and a sliding block I connected with the mounting frame slides on the surface of a sliding rail I, so that the polishing wheel is close to the surface of the cable body to polish the surface of the cable body, the surface of the cable body is polished by means of surface contact of the polishing wheel and the cablebody, and the polishing amount of the polishing wheel to the cable body can be controlled precisely by controlling the distance of the linear motor II shifting on the linear slideway II, so that the polishing precision of the cable is improved greatly, and the processing rejection rate of the cable is reduced.

Description

technical field [0001] The invention relates to the technical field of cable preparation, in particular to a cross-linked polyethylene insulated halogen-free low-smoke flame-retardant polyolefin sheathed power cable. Background technique [0002] Power cables are mainly cables used to transmit and distribute electrical energy. It is often used in the lead-out lines of urban underground power grids and power stations. In power lines, the proportion of cables is gradually increasing, so power cables of various performance types should be produced, especially fire-resistant power cables. As lead-out lines, the fire-resistant performance Not only good, but also have strong mechanical properties. [0003] After the current cross-linked polyethylene insulated low-smoke halogen-free flame-retardant polyolefin sheathed power cables are produced, the ports of the cables need to be polished to fix the connectors at the ports of the cables and connect the cables , but most of the exi...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a cross-linked polyethylene insulated low-smoke halogen-free flame-retardant polyolefin sheathed power cable, which solves the problem that most existing cable polishing devices are hand-held and it is difficult to fix the cable , it is inconvenient for the polishing treatment of the cable, and it is easy to cause the cable to be unusable due to excessive polishing of the cable, and the problem of high cable processing scrap rate
