Abstract

The utility model discloses a cold-resistant elevator flat cable which comprises a plurality of parallel wire cores, wherein each wire core is composed of a conductor in the middle and an insulating layer outside the conductor; a sheath layer is arranged outside the wire cores; isolation oil is added between the wire cores and the sheath layer; the conductors are formed by binding and twisting Category-5 soft copper conductors and have a pitch ratio of 14 to 20; and both the insulating layers and the sheath layer are made of Buna-N PVC (polyvinyl chloride) materials with low temperature resistance of subzero 40 DEG C. According to the utility model, the cold-resistant elevator flat cable has better flexibility and higher strength relative to PVC materials, and by testing, the strength of the cold-resistant elevator flat cable is commonly in the range of 15MPa and the elongation of the cold-resistant elevator flat cable can reach 500 percent, so that various quality problems caused by reduction of the flexibility of the elevator cable under a cold condition are effectively solved. Moreover, the added isolation oil plays a role of preventing adhesion and lubricating, so that the deflection performance of the cable can be slightly promoted.

Description

A kind of cold-resistant elevator flat cable
Technical field
The utility model relates to a kind of power cable, specifically is a kind of cold-resistant elevator flat cable.
Background technology
What existing elevator cable insulation and sheath material generally adopted is soft polyvinyl chloride, and it can satisfy the requirement of most of elevator cable, but under the very low environment of northern amblent air temperature; Common elevator cable obviously can not satisfy his weather requirement; The condition that common elevator cable lays and moves all can not be lower than 0 ℃, and the temperature in northern winter is usually all below 0 ℃, along with the reduction of temperature; The weak degree of PVC plastics declines to a great extent; The plastics hardening is and crisp, and its sheath of operation cable is easy to cracking under this temperature, because the conductor of cable hardening the inside opens circuit owing to long-play; Cable life declines to a great extent, and has all brought unnecessary trouble with safeguarding for the user.
The utility model content
The utility model technical problem to be solved provides a kind of elevator cable with good cold tolerance ability, and it still has enough pliabilitys in cold conditions, has prolonged the useful life of cable.
The described a kind of cold-resistant elevator flat cable of the utility model comprises some cores that are arranged in parallel, and said core is made up of the conductor and the outer insulating barrier of conductor of centre, at the core peripheral hardware restrictive coating is arranged, and between core and restrictive coating, adds and isolates oil.
Said conductor is that the 5th type of soft copper conductor transmitted beam strand forms, and pitch is than 14 ~ 20.
Said insulating barrier and restrictive coating all adopt the fine PVC material of low temperature resistant-40 ℃ fourth.
The beneficial effect of the utility model:
The structure of the utility model insulating barrier and restrictive coating makes the better intensity of its pliability bigger; Through its intensity of overtesting generally in the 15MPa scope; Percentage elongation can reach more than 500%, and this efficiently solves the various quality problems that elevator cable descends and brings owing to pliability under cold conditions.Add and isolate oil, play preventing adhesion and lubricated effect, the rich performance of song of cable can slightly be promoted.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; A kind of cold-resistant elevator flat cable of the utility model comprises some cores that are arranged in parallel, and said core is made up of the conductor 1 and the outer insulating barrier 2 of conductor of centre; At the core peripheral hardware restrictive coating 3 is arranged, between core and restrictive coating 3, add and isolate oil.Conductor 1 is that the 5th type of soft copper conductor transmitted beam strand forms, and pitch is than 14 ~ 20.Insulating barrier 2 all adopts the fine PVC material of low temperature resistant-40 ℃ fourth with restrictive coating 3.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement, these improve the protection range that also should be regarded as the utility model.
