Problems solved by technology

[0004] The traditional cable structure with the highest flame retardant grade is FEP insulation plus PVC sheath, which has high production costs. FEP is Teflon containing halogen fluorine, which will produce halogen when burned, which is harmful to human body and has poor safety performance, which cannot meet the requirements of CPR regulations.

Embodiment Construction

[0024] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0025] Such as figure 1 As shown, a low-smoke, halogen-free and highly flame-retardant communication cable includes several conductors 1, an HDPE insulating layer 2 arranged outside each of the conductors 1, and a sheath layer 3 covering all the conductors 1, arranged on The tape layer 4 outside the sheath layer 3 and the braided layer 5 arranged outside the tape layer 4 . The cladding layer 4 includes a first mica tape layer and a second mica tape layer. The first mica tape layer wraps the mica tape longitudinally outside the sheath layer 3; the second mica tape layer wraps around the outside of the first mica tape layer. The braided layer 5 is made of glass fiber yarn.

Abstract

The invention relates to the technical field of cables and in particular relates to a low-smoke and halogen-free high-flame-retarding communication cable and a manufacturing method of the low-smoke and halogen-free high-flame-retarding communication cable. The low-smoke and halogen-free high-flame-retarding communication cable comprises a plurality of conductors, an HDPE (High-density Polyethylene) insulating layer arranged on the outer part of each conductor, a protective sleeve layer for covering all the conductors, a belting layer arranged at the outer part of the protective sleeve layer and a braided layer arranged at the outer part of the belting layer. The cable provided by the invention has the advantages of high temperature resistance, combustion resistance, low cost, environmental friendliness, cleanness, safety, low combustion energy and the like.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a low-smoke, halogen-free and highly flame-retardant communication cable and a manufacturing method thereof. Background technique [0002] With the rapid development of data communication and network information technology and the continuous improvement of computer performance, the application of 10 Gigabit copper Ethernet has become the mainstream of data center. The problem of cable fire protection will undoubtedly attract more and more attention from the domestic integrated wiring market. The construction products sold and circulated in the EU market will implement the new EU CPR regulations from July 1, 2013 to officially replace the old building products. Product CPD Directive. The full name of the CPR regulation is the EU Construction Products Regulation, which aims to ensure the effectiveness and efficiency of the relevant EU market by clearly specifying the performance re...
