Problems solved by technology

[0002] In the prior art, the air guide tube inside the inert gas shielded cable is designed as a single pipe, and there is no support structure inside. When it is used under heavy pressure from an external force or when it is bent and stretched by a large force, the air guide tube may appear. Bending and deformation seriously affect the service life of the cable

Abstract

The invention discloses a reinforced inert gas protecting composite cable which comprises an inert gas guiding tube. The gas guiding tube is internally provided with a cross supporting frame. Three communication cables and five power cables are arranged outside the gas guiding tube. The communication cable comprises an innermost communication conductor. According to the reinforced inert gas protecting composite cable, the cross supporting frame is added in the gas guiding tube. The cross supporting frame can effectively improve pressure resistance of the gas guiding tube for preventing collapse deformation in bearing a relatively high pressure. Furthermore the communication cables and the power cables are separately arranged. The communication cable is provided with an inner shielding layer which can effectively prevent signal interference, and the communication cable is provided with an outer shielding layer which prevents signal loss. Furthermore the inner wall of the gas guiding tube is provided with an arc-shaped chute. The end of the cross frame is provided with a corresponding arc-shaped supporting plate. Therefore the cross frame can be conveniently mounted in the gas guiding tube and further can be conveniently detached from the gas guiding tube.

Description

technical field [0001] The twisted-pair cable of the invention specifically relates to a reinforced inert gas-protected composite cable. Background technique [0002] In the prior art, the air guide pipe inside the inert gas protection cable is designed as a single pipe without a support structure inside. When it is under heavy pressure from an external force or is bent and stretched by a large force during use, the air guide pipe may appear Bending and deformation seriously affect the service life of the cable. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies in the prior art and provide a reinforced inert gas-protected composite cable. The technical solution is as follows: [0004] A reinforced inert gas-protected composite cable, including an inert gas air guide tube; a cross support frame is installed inside the air guide tube; three communication cables and five power supply cables are arranged outside the air gui...
