Description
Technical field
The utility model relates to a kind of control cable, a kind of novel low smoke zero halogen fire resistant fireproof control cable of saying so more specifically.
Background technology
As everyone knows, electric wire is called as the blood vessels and the nerve of people's productive life: transmission ﹠ distribution electric energy, transmission information, but be again " blasting fuse " of fire hazardous simultaneously, also burning thereupon of common cable during breaking out of fire, cause even more serious " spot fire " accident, cause bigger loss for people's lives and properties.Therefore in many important events, as subway, station, market etc., just in case during breaking out of fire, the evacuating personnel escape, the illumination of passage, fireproof alarming device, automatic fire-fighting facility and other emergency set, require all that cable can keep normal power-up at the appointed time when fire takes place, have the LSZH characteristic when requiring cable fire simultaneously.Therefore, people develop the fire-resistant serial cable of LSOH anti-flaming.
LSOH anti-flaming fire-resisting cable: refer to that sample burns under the regulation experimental condition in flame, still can keep the performance of normal operation within a certain period of time, have the LSZH characteristic simultaneously during cable fire.Its basic characteristic is exactly: control cable still can be kept the operate as normal of this circuit a period of time and have the LSZH characteristic under burning condition.Generally be exactly, can keep the normal power supply of a period of time when fire takes place, to keep illumination and transmission signals, LSZH burns simultaneously, and the protection personnel have the time enough safe escape, and is beneficial to fire extinguishing and reduces loss.
At present, common LSOH anti-flaming fireproof control cable is the wrapped fireproof control cable of mica tape both at home and abroad, and its structure is followed successively by from inside to outside: conductor-wrapped mica tape-insulation-stranding is wrapped, filling-shielding-armouring-sheath; What wherein play fire-resistant effect is mica tape; Insulating material is identical with the general control cable; Filling, wrapped material can adopt common material or flame retardant type material as required; Sheath material can be selected flame-proof PVC, low cigarette, low halogen, Halogen, hypotoxicity sheath material for use according to fire resistance rating.
The mica tape that plays the hot-face insulation effect is to be equipped with suitable adhesive by mica paper and reinforcement with electrician's alkali-free glass fiber cloth to cut the insulating material that forms after curing drying, costs an arm and a leg, and it is very big to account for cable cost proportion.Simultaneously in producing wrapped process, mica powder is reeled and is easy to come off along with the bending of belt, directly influences the fire resistance of product, and mica tape makes moist easily and causes control cable to puncture; Mica tape and reinforced layer must adopt wrapped mode to be coated on the control cable conductive surface, the process structure complexity, and wrapped speed is slow, efficient is low, influences production efficiency of products.In addition, the permission working temperature of different mica tapes differs greatly processing difficulties.More than various defectives cause the control cable fire resistance instability that adopts mica tape fire-resistant, Technological Economy is not high.
In the period of the positive fast development of 21 century urban rail transit in China, track traffic is with the huge market demand of serial electric wire, and industrialization prospect is wide, and used cable mostly requires low cigarette not have (low) halogen, characteristic such as fire-retardant, fire-resistant.Along with the requirement of domestic and international electric wire fireproof is progressively higher, traditional fire-resisting cable is subjected to the limitations restrict of material and structural manufacturing process, researches and develops novel suitable track traffic and more and more comes into one's own with electric wire fireproofing of cable refractory material, new structure technology.
The utility model content
The purpose of this utility model is to solve above-mentioned deficiency, a kind of novel low smoke zero halogen fire resistant fireproof control cable is provided, the utility model has overcome the deficiencies in the prior art, do not re-use expensive mica tape refractory material, but by adopting the novel structure and the material of function admirable, when satisfying the low fire-retardant fire resistance of Halogen, reduce cost greatly, have excellent technical and economy.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
Track traffic of the present utility model novel low smoke zero halogen fire resistant fireproof control cable, be followed successively by flexible conductor, insulating barrier, packed layer, stranding lapping layer, woven shield, isolation jacket layer, steel-tape armouring layer and oversheath by internal layer to skin, the endothecium structure of described cable is successively by the layer structure integral coating.
As optimal way: the quantity of described flexible conductor is two to 37.
As optimal way: described flexible conductor is zinc-plated soft copper conductor.
As optimal way: described insulating barrier is a fireproof electric wire dedicated ceramic silicon rubber.
As optimal way: described packed layer is the fire-retardant packed layers of asbestos, is applied to the filling of multicore cable, so that cable is fire-resistant, rounding.
As optimal way: described stranding lapping layer is the fireproof glass silk ribbon.
As optimal way: described woven shield is formed by zinc-plated soft round copper wire braiding.
As optimal way: described isolation jacket layer is a fireproof electric wire dedicated ceramic silicon rubber.
As optimal way: described steel-tape armouring layer is a galvanized steel strip.
As optimal way: described silicon rubber oversheath is a fireproof electric wire dedicated ceramic silicon rubber.
Compared with prior art, the beneficial effects of the utility model are:
The utility model adopts the novel structure and the material of function admirable, makes flexible multicore fire resistant fireproof control cable, can be in low temperature environment tear-proof, the high load capacity that can bear under the high drop condition continue to reverse.Adopt potteryization silicon rubber as insulating layer material, make insulating barrier not only to insulation function but also play fire-resistant function, simplified the construction of cable, by the multi-layer ceramics silastic structure is set, cable is carried out multiple protective in addition, fail safe is higher.
The insulating barrier of LSOH anti-flaming fireproof control cable described in the utility model, external sheath layer and separation sleeve layer material are the potteryization silastic-layers, at high temperature be sintered into pottery rapidly, cable not fusion under the hot environment below 1300 ℃, do not drip, play firm protective effect, guaranteed the normal operation of control cable system, and the discharging of non smoke, poison gas, satisfy the national standard requirement fully through evidence; Be adapted at using in control and the signal transmission system, shape can be used and remain unchanged in fire, circuit is unobstructed under the situation of guarantee fire, and do not re-use expensive mica tape refractory material, simple in structure, easy to process, flow process is simple, be fit to suitability for industrialized production, be easy to promote, have excellent Technological Economy.
