Abstract

The utility model relates to the field of cables, in particular to a high flame-retardant environment-friendly cable. The existing high flame-retardant environment-friendly cable has the deficiencies of having poor flame retardancy, causing secondary disasters easily, and the like. The utility model aims at providing a high flame-retardant environment-friendly cable which comprises conductors, cable cores formed by insulating layers, a polyolefin filled layer and an outer sheath layer, wherein the insulating layers wrap the conductors, thus forming the cable cores; the polyolefin filled layer lapping is filled among the cable cores, thus forming the cable; and the cable is wrapped with the outer sheath layer. The insulating layer of the high flame-retardant environment-friendly cable can insulate air more effectively and reduce toxic gas and smoke in fire, thus reducing the disaster degree and environment pollution caused thereby.

Description

The environment protection high flame resistance cable

Technical field

The utility model relates to field of cables, a kind of high flame-retardant cable of more specifically saying so.

Background technology

Along with the mankind to preserving the ecological environment and the pay attention to day by day of self health, the environmental-protecting performance of cable has been proposed higher more fully requirement.At present, domestic flame-retardant electric wire and cable is divided into general flame-retardant electric wire and cable, low smoke and low halogen electric wire and low-smoke halogen-free flame-retardant electric wire and cable usually, these flame-retardant electric wire and cable products are fire-retardant based on Halogen, these flame retardant cables normally add fire retardants such as phosphorous in sheath and insulating barrier, at high temperature generate halogen hydracid, phosphoric acid etc., further the stable volume phosphoric acid of dehydration generation covers by the combustion cable surface, with blocking oxygen, thereby stops burning to further develop.But, because packed layer is shaky, make in the insulating barrier of cable and the air oxygen obstruction abundant inadequately, still discharge virose HCL gas during burning, and have a large amount of smog and corrosivity halide to produce, therefore damage (HCL gas stimulates human organ that the people is suffocated) to personnel, also highly sophisticated device and various device are caused corrosion, return rescue and bring very large difficulty, and cause harm such as environment, promptly so-called " secondary disaster ".

The utility model content

Poor in order to overcome existing environment protection high flame resistance cable-flame retardant, cause deficiencies such as secondary disaster easily, the purpose of this utility model is: a kind of environment protection high flame resistance cable is provided.

The technical scheme that its technical problem that solves the utility model adopts is as follows: a kind of environment protection high flame resistance cable, and it comprises conductor, the cable core that insulating barrier constitutes, polyolefin packed layer, lapping layer, external sheath layer; Insulating barrier is wrapped in conductor and forms cable core outward, and lapping layer is wrapped in outside the cable core, and filled polyolefin packed layer between the cable core forms cable in the lapping layer, and cable is wrapped up by external sheath layer.

The cross section of described conductor is circular or fan-shaped.Compared with prior art, the beneficial effects of the utility model are:

A kind of environment protection high flame resistance cable is provided, intercepts, the generation of toxic gas and smog when reducing the fire generation, thereby the environmental pollution that reduces the disaster degree and bring thus in the hope of forming more effective air to the insulating barrier of cable.

1, present technique can be implemented good air to insulating barrier and intercept by form the polyolefin packed layer between each cable core, the generation of toxic gas and smog when effectively reducing the fire generation, the environmental pollution that reduces the disaster degree and bring thus.

2, present technique meets specific environmental requirement in production, use and processing procedure, compared with the prior art, has low toxicity environment-friendly advantage such as do harm to less, economize on resources, more useful to biological environment, be the excellent two excellent technology of Functionality, quality and appealing design, environmental behaviour, help in consumer mind, establishing real Green Product image.

3, the utilization of present technique meets the national sustainable development strategy, help the long-term benign development of enterprise, have good high temperature resistant, weather resisteant, characteristic such as corrosion-resistant, present technique institute composition thermal conductivity, insulating properties, mechanical property and processing characteristics excellence can reach the purpose of low cigarette, low toxicity and high flame retardant.

4, present technique is simple in structure, and is easy to implement.

Description of drawings

Fig. 1 is the structural representation of the utility model environment protection high flame resistance cable.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified, but not as to qualification of the present utility model.

See also the embodiment of the utility model environment protection high flame resistance cable shown in Figure 1, referring to Fig. 1, form is provided with insulating barrier 2 and forms cable core on the top layer of conductor 1 routinely, and the cable appearance is set to external sheath layer 5; In this enforcement, form polyolefin packed layer 3 between each cable core, polyolefin packed layer 3 is wrapped with lapping layer 4.

Cabling process flow process following steps in the enforcement are carried out:

1, stranded copper conductor 1;

2, the appearance extruded insulation layer 2 at conductor 1 forms insulated wire cores;

3, the polyolefin of filling high flame retardant between each core is filled aspect 3;

4, carry out wrappedly in the outside of polyolefin packed layer 3, form lapping layer 4;

5, extrude formation external sheath layer 5 in the outside of lapping layer 4.

According to the size that transmits electric energy, the shape of conductor 1 can or be fan-shaped for as described in Figure 1 circular; For 35mm ²Following cross-sectional area of conductor adopts circular, for 35mm ²Above cross-sectional area of conductor adopts fan-shaped, and conductor structure is reasonable.

Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection range of the present utility model.
