A waterproof and heat-resisting compensating lead wire for ships

Abstract

The invention relates to a waterproof and heat-resisting compensating lead wire for ships. The waterproof and heat-resisting compensating lead wire comprises insulated wire cores each consisting of aconductor and an insulation layer; every two positive-pole and negative-pole insulated wire cores are subjected to pair twist and wrapped by a polyester belt to form a wire pair wrapping layer; a wirepair shield layer is arranged on the outside of each wire pair wrapping layer; at least two groups of wire pairs are twisted to form a cable core and a filling layer is arranged in the gap of the cable core; the outer side of the cable core is successively provided with a cable wrapping layer, a braid layer, a shield wrapping layer, a longitudinal wrapping layer, a bonding layer, an armor layer and an outer protection layer. The waterproof and heat-resisting compensating lead wire for ships has the characteristics of excellent electrical properties, accurate sensing and control of temperature, wide using temperature range, heat resistance, pressure resistance, water resistance, tear resistance and environmental protection and can be widely applied to device temperature control connectionbetween temperature measuring instrument cold ends and temperature measuring instruments in places like ships, large working vessels and offshore oil platforms.

Description

technical field [0001] The invention relates to the field of cables, in particular to a waterproof and heat-resistant compensating wire for ships. Background technique [0002] At present, with the rapid development of China's ship industry, the supporting ship cables are more and more widely used. As the temperature compensation wire used in the control system of the ship, it is called the control nervous system of the ship. , plays an important role in the development of China's shipbuilding industry. [0003] The development of domestic marine cables started late, and the technical level of various manufacturers is uneven. In addition, in recent years, international ships have higher and higher requirements for marine compensation wires. As a result, many manufacturers cannot design and produce products that meet the technical requirements due to limited technical strength. required marine cable products. Many large shipbuilding factories mostly use imported products fo...

Problems solved by technology

[0003] The development of domestic marine cables started late, and the technical level of various manufacturers is uneven. In addition, in recent years, international ships have higher and higher requirements for marine compensation wires. As a result, many manufacturers cannot design and produce products that meet the technical requirements due to limited technical strength. Required Marine Cable Products

Many large shipbuilding factories mostly use imported products for ship cables. However, imported cables are expensive and have a long production cycle, which is not conducive to the development of China's shipbuilding industry.
