Abstract

The invention relates to the technical field of cables and provides an insect-resistant composite cable comprising conductors (1). Each conductor (1) is wrapped with an insulation layer (2), the insulation layers (2) are wrapped with a shielding layer (4) which is wrapped with an internal sheath layer (5), the internal sheath layer (5) is wrapped with a flame retardant layer (8) which is wrapped with an external sheath layer (9), cavities (10) are arranged in the external sheath layer (9), insect repellant is arranged in each cavity (10), optical fibers (6) are arranged in the internal sheath layer (5), a waterproof layer (7) is arranged outside each optical fiber (6), each waterproof layer (7) comprises a reinforcing layer, a base layer, a water resisting layer and a coverage layer which are adhered in sequence, the reinforcing layer is copper wire gauze, both the base layer and the coverage layer are non-woven fabric, the water resisting layer is made of mica tapes or glass fibers, the flame retardant layer (8) comprises a mica layer and a basalt fiber braided layer wrapping the mica layer, and the thickness of the mica layer is 0.2-0.9mm.

Description

technical field [0001] The invention relates to the technical field of cables and provides an insect-resistant composite cable. Background technique [0002] The existing cables have problems such as mouse bites and termites during use, and the waterproof and moisture-proof capabilities are not good. [0003] Since the world's first low-voltage power cable (rubber belt wrapped copper conductor) was produced in 1836, wire and cable have developed into a large product category with a wide range of uses and varieties. After more than 70 years of development, my country's wire and cable industry has also made great progress. With the rapid development of China's wire and cable industry, the number of new enterprises has been increasing, and the overall technical level of the industry has been greatly improved. At present, there are about 5,000 state-owned and above-scale enterprises in my country's wire and cable industry, including 19 large-scale enterprises, whose total outp...
