Description

The explosion-proof instrument that blocks water connects cable

Technical field

This utility model relates to a kind of cable, particularly relates to a kind of explosion-proof instrument that blocks water and connects cable.

Background technology

In explosion-proof, water resistance, cable is for requiring that higher occasion can normal transmission electric energy in the case of occurring spy to become It is particularly important, owing to Sefe antiexplosion circuit distributing system and Aulomatizeted Detect control system use occasion are special, this Just require that cable must have resistance waterproof anti-explosion and interference free performance, otherwise do not reach use and require to make equipment produce misoperation Or initiation fire blast, cause heavy losses to the lives and properties of the country and people.

Utility model content

This utility model provides a kind of compact conformation, wear-resisting, waterproof and dampproof, explosion-proof, anti-dry to solve problem above Disturb effective, safety coefficient is high, length in service life explosion-proof block water instrument connect cable.

The technical solution of the utility model is: described cable includes seven cable cores, and described cable core includes that anaerobic is tin plating Copper conductor, sets gradually outside described conductor in polyethylene layer, tinned copper wire braiding internal shield, polyethylene from the inside to the outside Sheath, the outer wrapped waterstop of seven described cable cores, aluminum plastic belt twining package tape is set outside described waterstop, outside described twining package tape Tin plating copper mesh braiding external shielding layer is set, half squash type polythene inner is set outside described external shielding layer, described in protect Layer is outer arranges abrasion resistant polyurethane outer jacket.

Seven described cable cores are uniformly arranged on cable center.

This utility model has the most wear-resisting, waterproof, explosion-proof and interference free performance, is widely used in explosion-proof, waterproof The occasion that performance requirement is high, is particularly well-suited to Sefe antiexplosion circuit transmission and connects use, and safety coefficient is high.Cable arranges plating Stannum soft stock conductor, soft easily welding does not aoxidizes, and simultaneously facilitates installation；Cable core shielding is outer arranges polyethylene sheath and after stranding always shields Half squash type polythene inner, good water-proof effect are set；Abrasion resistant polyurethane outer jacket is set, from source, serves one very Good protective effect, has the most wear-resisting and gear tide performance.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

In figure, 1 is conductor, and 2 is insulating barrier, and 3 is internal shield, and 4 is inner sheath, and 5 is waterstop, and 6 is twining package tape, outside 7 are Screen layer, 8 is sheath, and 9 is outer jacket.

Detailed description of the invention

The explosion-proof instrument that blocks water connects cable, and described cable includes seven cable cores, and described cable core includes anaerobic tin-coated copper Conductor 1, described conductor 1 is outer sets gradually polyethylene layer 2, tinned copper wire braiding internal shield 3, polyethylene from the inside to the outside Inner sheath 4, the outer wrapped waterstop 5 of seven described cable cores, aluminum plastic belt twining package tape 6 is set outside described waterstop 5, described around Tin-coated copper net braiding external shielding layer 7 is set outside band 6, half squash type polythene inner 8 is set outside described external shielding layer 7, Arranging abrasion resistant polyurethane outer jacket 9 outside described sheath 8, seven described cable cores are uniformly arranged on cable center.
