Abstract

The utility model relates to a multi-core aluminium alloy conductor fireproof cable, comprising a plurality of cores. An outer side of each core is coated with an insulating layer. An outer side of the plurality of cores is coated with a taped covering. A fireproof filling material is filled between the taped covering and the cores and between adjacent cores. An outer side of the taped covering is coated with a secondary outer layer. An outer side of the secondary outer layer is coated with an outer layer. The cores are aluminium alloy conductors and are uniformly distributed at the inner side of the taped covering. The insulating layers are made of ceramic silicone rubber. The fireproof filling material is fireproof filling ropes. The beneficial effects are that the cores uses aluminium alloy as conductors, the outer side of each core is provided with the insulating layer and a fireproof filling layer, and a fireproof function is fully achieved; the secondary outer layer is a copper pipe and can prevent the cores from being broken when folded to prevent the conducting function from being affected; and the outer layer is a low-smoke halogen-free material, so that damage of flue gas generated in the combustion of the cable on a human respiratory system is reduced, and an object of environmental protection is achieved.

Description

A kind of multicore aluminium alloy conductor fireproof cable

Technical field

The utility model relates to a kind of multicore aluminium alloy conductor fireproof cable.

Background technology

At present, cable is the main tool of transporting in shop in daily life, the decoration that many modernizations obtain the important public places such as office building, hotel, market, subway, railway station, residential building is more and more luxurious, the combustible using is more and more, for preventing fire, the circuit of finishing must adopt the cable that fire protecting performance is good, to reduce fire damage.Owing to containing a large amount of halogens in fire retardant, electric wire will be emitted a large amount of poison gas, acid mist and flue gas when burning, these combustion products not only threat to life are complete, contaminated environment, also can cause the heavy corrosion of equipment and building, withdraw and rescue property to fire extinguishing, fire-extinguishing and lifesaving and personnel and cause very large inconvenience.

Utility model content

The purpose of this utility model is to provide a kind of multicore aluminium alloy conductor fireproof cable, to overcome prior art above shortcomings.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of multicore aluminium alloy conductor fireproof cable, comprise some cores, each core outside is all enclosed with insulating barrier, described some cores outside is enclosed with lapping layer, between described lapping layer and core and adjacent core, be all filled with fire-resistant packing material, described lapping layer outside is enclosed with time skin, and described time outer field outside is enclosed with skin.

Further, described core is aluminium alloy conductor, and described core is evenly distributed on lapping layer inner side.

Further, described insulating barrier is ceramic silicon rubber.

Further, described fire-resistant packing material is fire-resistant gasket for packing.

Further, described lapping layer is refractory glass fiber silk cloth.

Further, described skin is copper pipe.

The beneficial effects of the utility model are: core adopts aluminium alloy to do conductor, and core outside is provided with insulating barrier and fire-resistant packed layer, and fully realizes fire-proof function; Inferior skin is copper pipe, can prevent that core is bent and causes core to disconnect, and affects conducting function; Skin is low smoke and zero halogen material, thereby the injury of the flue gas producing while slowing down cable fire to human respiratory realizes the object of protection of the environment.

Accompanying drawing explanation

With reference to the accompanying drawings the utility model is described in further detail below.

Fig. 1 is the structural representation of multicore stranded conductor fireproof cable described in the utility model embodiment.

In figure:

1, core; 2, insulating barrier; 3, fire-resistant packing material; 4, lapping layer; 5, inferior skin; 6, skin.

Embodiment

As shown in Figure 1, a kind of multicore aluminium alloy conductor fireproof cable described in the utility model embodiment, comprise some cores 1, each core 1 outside is all enclosed with insulating barrier 2, described some cores 1 outside is enclosed with lapping layer 4, between described lapping layer 4 and core 1 and adjacent core 1, be all filled with fire-resistant packing material 3, described lapping layer 4 outsides are enclosed with time skin 5, and the outside of described time outer 5 is enclosed with outer 6.

Described core 1 is aluminium alloy conductor, and described core 1 is evenly distributed on lapping layer 4 inner sides.Described insulating barrier 2 is ceramic silicon rubber, and described fire-resistant packing material 3 is fire-resistant gasket for packing, and described lapping layer 4 is refractory glass fiber silk cloth, and described time outer 5 is copper pipe.

During concrete making, inferior outer 5 use copper strips argon fluorine are welded into copper pipe and prick line, and outer 6 use low smoke and zero halogen materials are coated, and test is by GB/T12666.6-2008 and BS6387-1994 standard.

The operating voltage of multicore aluminium alloy conductor fireproof cable described in the utility model is 750/450V.

The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection range of the present utility model.
