Abstract

The invention discloses a cold-resistant data transmission cable, which comprises a cable core consisting of stranded conductors and filling ropes, and a cold-resistant belting layer, a cold-resistantinner sleeve layer, a metal braided layer and a cold-resistant outer sheath which sequentially wrap the outer side of the cable core, an insulating layer is arranged on the surface of the stranded conductors; raw materials of the cold-resistant inner sheath layer and the cold-resistant outer sheath comprise the following components by weight: 15-40 parts of methyl vinyl phenyl silicone rubber, 25-40 parts of 1, 4-polybutadiene rubber, 10-30 parts of linear low-density polyethylene, 3-9 parts of zinc oxide, 2-6 parts of calcium stearate, 2-8 parts of a cross-linking agent, 1-3 parts of an assistant cross-linking agent and 0.6-2 parts of an anti-aging agent. The content of phenyl in the methyl vinyl phenyl silicone rubber is 5-25%, and the 1, 4-polybutadiene rubber is cis-1, 4-polybutadienerubber. The cold-resistant grade of the cold-resistant data transmission cable can reach -70 DEG C, and the problems that an existing product is flattened and snapped during laying and a sheath cracks during laying and using in severe cold areas are effectively solved.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cold-resistant data transmission cable. Background technique [0002] In recent years, the development of wire and cable varieties has shown a trend of diversification. It has changed from pure power transmission function to multi-function, that is, new features have been added according to different uses, such as: low-smoke and zero-halogen, low-smoke and low-halogen, Cold-resistant, waterproof, rodent-proof, termite-proof, etc., in some special occasions, it is even required that the cable has two or more comprehensive characteristics. [0003] In the alpine regions such as northern and western my country, the temperature in winter is low, the time is long, and the temperature difference between day and night is large. For example, the lowest temperature in Xinjiang is -40°C, the lowest temperature in Ningxia is -33°C, the lowest temperature in Shanxi is -28°C, and the lowest...
