Anti-interference buffer type composite optical cable

Abstract

The invention discloses an anti-interference buffer type composite optical cable, comprising a main body, a first insulation filling layer, a power line and a control line, wherein the power line is embedded in the main body and arranged at a middle position, the two control lines are arranged at the upper side and the lower side of the power line by taking the power line as a symmetry axis, and the first insulation filling layer fills a gap between the power line and the control lines; the power line is in a shape like a dumbbell, and a cavity is formed inside the power line; the shielding strip is arranged, so that mutual interference between the control line cores can be avoided; and the buffer convex body is arranged, so that better buffer protective effect is realized on the control lines, and the control lines are avoided from being deformed due to strong extrusion. The anti-interference buffer type composite optical cable disclosed by the invention is reasonable in layout and good in insulativity, high temperature resistance, corrosion resistance and flame resistance and also has good anti-pull, compression-resistant and sag-resistant capabilities, so that use security and reliability of the cable are greatly improved.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an anti-interference buffer type composite optical cable. Background technique [0002] Cable is a common data signal transmission device, which has the advantage of large communication capacity. One cable sets up multiple cables to transmit multiple signals at the same time, but occasionally there will be signal interference problems; with the advancement of technology, cables are used in daily life In various fields in China, people have higher and higher requirements for cable specifications; due to the harsh environment of cables, cables are required to have high temperature resistance, ozone resistance, salt spray resistance, heat and humidity resistance, acid and alkali resistance, halogen-free and low-smoke characteristics, generally Cables make it difficult to keep the system safe to use. In use, it is necessary not only to avoid mechanical damage, insulation damage, insu...
