High-rate tensile bus cable

Abstract

The invention relates to the technical field of bus cables, in particular to a high-rate tensile bus cable. The high-rate tensile bus cable comprises a multi-core wire set, a copper core set and an environmentally-friendly flame-retardant outer sheath, the outermost outer surface of the multi-core wire set comprises a wire set polyethylene insulation thin layer, the inner side of the wire set polyethylene insulation thin layer is covered with a wire set wrapping layer, and the inner side of the wire set wrapping layer is composed of a polyester tape layer, the inner side of the environmentally-friendly flame-retardant outer sheath is coated with a polyurethane layer, solid carbon dioxide powder is directly added in each copper core set and the multi-core wire set to improve the safety of the usage of the wire core, avoid the burning of the protection layer at the internal portion caused by too high temperature due to misuse of the internal copper core wires, improve the fire resistanceof the wire cores when used and improve a certain safety, and an aramid yarn flexible reinforce is added to improve the flexibility of the whole cable in the usage process and improve the tensile effect. The whole practicability is high, and the usage effect is better compared to a traditional mode.

Description

technical field [0001] The invention relates to the technical field of bus cables, in particular to high-speed tensile bus cables. Background technique [0002] In the process of modern information development, cables are widely used. The bus cable uses digital communication technology for the bus system. With the continuous development of national defense technology, more and more bus cables are used in special fields such as weaponry and ship industry. This requires the bus cable to be environmentally friendly, waterproof and Flame retardant and tensile properties, etc., but the special properties of the existing bus cables are not perfect, and cannot meet the requirements of different bus systems. The internal conductivity of the existing flame retardant bus cables is poor, which easily causes heat. The flame-retardant type only means that it is not easy to catch fire or the combustion after fire is limited to a certain range. The existing waterproof and flame-retardant ...

The bus cable uses digital communication technology for the bus system. With the continuous development of national defense technology, more and more bus cables are used in special fields such as weaponry and ship industry. This requires the bus cable to be environmentally friendly, waterproof and Flame retardant and tensile properties, etc., but the special properties of the existing bus cables are not perfect, and cannot meet the requirements of different bus systems. The internal conductivity of the existing flame retardant bus cables is poor, which easily causes heat. The flame-retardant type only means that it is not easy to catch fire or the combustion after fire is limited to a certain range. The existing waterproof and flame-retardant bus cables are prone to signal interference in fire signal transmission. The performance of communication cables is generally poor, and the shielding effect is poor. Communication anti-interference is low, and in the actual use process, it is found that the energy consumption is more serious, and the external insulation layer is more damaged during long-term use, and the signal transmission signal of the internal signal line is poor according to the total length of the cable. , and the signal line is strongly disturbed by the power line
