Low-smoke halogen-free flame-retardant power cable

Abstract

The invention discloses a low-smoke halogen-free flame-retardant power cable which comprises a core wire, a filling layer, a wrapping layer and a sheath layer. The core wire comprises a conductor andan insulating layer extruded outside the conductor. The insulating layer is made of a cross-linked polyethylene material. The sheath layer is made of a safe environmentally-friendly granular low-smokehalogen-free flame-retardant sheath material. An oxygen barrier layer and a glass fiber tape layer are arranged from the inside out between the wrapping layer and the sheath layer. According to the invention, the insulating layer is made of the cross-linked polyethylene material; the sheath layer is composed of the low-smoke halogen-free flame-retardant environmentally-friendly sheath material; and the low-smoke halogen-free flame-retardant power cable has the advantages of softness, tensile strength, low-temperature performance, great halogen-free and low-smoke performances, great compatibility and great flame-retardant performance.

Description

technical field [0001] The invention relates to the technical field of elevator cables, and mainly relates to a low-smoke, halogen-free, flame-retardant power cable. Background technique [0002] With the maturity of elevator technology in our country, more and more elevators are used. During the elevator installation process, cables need to be installed to provide power to the elevator. With the lifting operation of the elevator, it is easier to damage the distribution cables or easily Signal interference is caused and the applicability and usefulness of the cable is limited. Elevators are essential transportation equipment in high-rise buildings. With the development of science and technology and the needs of people's work and life, some activities such as communication and monitoring are required in the elevator. For this reason, it is necessary to hang relevant signal lines, Repeated lifting and lowering together with the elevator, during use, the cable is frequently re...

Elevators are essential transportation equipment in high-rise buildings. With the development of science and technology and the needs of people's work and life, some activities such as communication and monitoring are required in the elevator. For this reason, it is necessary to hang relevant signal lines, Repeated lifting and lowering together with the elevator, during use, the cable is frequently retracted and pulled, which affects the service life, may break, damage, and cause other related function interruptions
