Abstract

The utility model relates to a waterproof instrument cable for vessels. An insulating layer is extruded and enwrapped on a conductor to form an insulated wire core; a unit group is formed by the insulated wire core; a cable core is formed by a plurality of unit groups; and an overall shielding layer, an armor layer and an outer sheath layer are arranged outside the cable core. The waterproof instrument cable is characterized in that the insulating layer extruded and enwrapped on the conductor is made of silane cross linked polyethylene or PE materials; each unit group is an twisted pair line group formed by stranding two insulated wire cores; a unit leading wire and a unit shielding layer are respectively arranged on each unit group; waterproof paste is filled in each unit group; the cable core is formed by a plurality of unit groups with different stranded pitches; and an overall leading wire is arranged outside the cable core; the waterproof paste is filled at the clearance in the middle of the cable core; the armor layer has a structure woven by a tinned steel wire; and the outer sheath is made of low fume and halogen-free flame retardant PE sheath materials or TPU elastic materials. The utility model not only has excellent electrical property, but also has the advantages of water tightness, corrosion resistance, low fume, flame retardance, environmental protection, and the like, and can effectively improve the quality of instruments and meters for the vessels in cable connection.

Description

A kind of water proof type naval vessel instrument cable

Technical field

The utility model relates to a kind of naval vessel instrument cable, relates in particular to a kind of water proof type naval vessel instrument cable, belongs to technical field of electric wires and cables.

Background technology

In recent years, along with the fast development of China's economic and science and technology, the shipping industry of China is grown up rapidly, and the shipbuilding tonnage ranks first in the world at present.For making great efforts to improve China's boats and ships corollary equipment production domesticization, realize that the technology upgrading of China's boats and ships relevant equipment is imperative.Particularly being referred to as the nerve and the blood vessel of boats and ships as the supporting electric wire of boats and ships, also is one of important corollary equipment that improves the whole equipment of boats and ships technical merit, is related to fail safe, reliability and the advance of boats and ships.Need use the cable with water-proof function at the boats and ships privileged sites, the water proof type cable uses very extensive in boats and ships, also can be applicable to control connection lines such as deepwater work instrument, instrument, robot simultaneously.But the conventional at present cable that uses can not satisfy the requirement of its water-proof function.

The utility model content

The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of water proof type naval vessel instrument cable is provided, it under normal circumstances requires to possess excellent electric performance, have characteristics such as high-transmission stability, low-loss, low electric capacity, low inductance, highly sensitive, high anti-electromagnetic interference, can have simultaneously characteristics such as waterproof, anticorrosion, low cigarette, fire-retardant, environmental protection again, in the hope of improving the quality of naval vessel instrument and meter stube cable.

The utility model technical solution problem adopts following technical scheme:

The utility model water proof type naval vessel instrument cable is that the insulating barrier that extrudes on conductor forms insulated wire cores, constitutes the unit group by insulated wire cores, and constitutes cable core, cable core by the unit group and have total screen, armour and external sheath layer outward;

Design feature of the present utility model is that the insulating barrier that extrudes on the described conductor is to be material with organosilane crosslinked polyethylene or PE; Described unit group is to thoroughly do away with the edge core by two to be twisted into the twisted pair wire group, is respectively equipped with unit drainage thread and unit screen on each unit group, and fills waterproof; Described cable core is formed cable by a plurality of unit with different twisting pitch, and total drainage thread is set outside cable core, and waterproof is filled at cable core intermediate gaps place; Described armour adopts the zinc-coated wire braiding structure; Described external sheath layer adopts low-smoke non-halogen flame-retardant PE protective cover material or TPU elastomeric material.

Compared with the prior art, the utility model beneficial effect is embodied in:

1, the utility model is provided with waterproof construction respectively in unit group and cable core, has favorable waterproof property;

2, in the utility model in the same cable core each unit group have different twisting pitch, reduced the influence of cross-talk to the cable transmission signal, guaranteed the stability of cable signal transmission, reduce the right electromagnetic coupled of line of cable simultaneously, realized transmission performances such as cable high transfer rate, low transmission impedance, low decay;

3, effective line that has reduced cable that is provided with of unit screen is done anti-ly in the utility model to an electromagnetism, and being provided with of the outer total screen of cable core reduced cable and surrounding environment is produced electromagnetic interference or surrounding environment cable is produced disturbed;

4, armour adopts the design of zinc-coated wire braiding structure in the utility model, can play the effect of cable suspension carrying cable weight on the one hand, can play the effect of anti-magnetic disturbance on the other hand;

5, external sheath layer adopts low-smoke non-halogen flame-retardant PE protective cover material or TPU elastomeric material in the utility model, and environmental protection, safety, recyclable repeated use have the performance of special adverse circumstances such as anti-naval vessel humidity, high salinity, difference variation are big;

6, the utility model structure is provided with rationally, manufactures easily, and cable electrical performance, mechanical and physical performance are good, can satisfy the specific requirement of waterproof, running environment and control technology on the naval vessel.Fire when burning amount of being fuming is low, does not produce halogen acid gas, and cable has not flame-retarding power energy, has satisfied modern instrument instrument cable performance demands.
