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.
