Description
Technical field
The present invention relates to communication optical cable CABLE MATERIALS, more particularly, to booster stage communication optical cable high flame resistance, low smoke compound electric
Cable material and its manufacturing process.
Background technology
Plenum rated cables high flame resistance, low smoke pvc composite is mainly used in the fire-retardant shield of cmp communication cable and optical cable
Layer material. fire safety is realized increasingly with people as flame retardant rating highest cmp cable in fire-retardant communication cable
Receive publicity and pay attention to. in the U.S., government has drawn the lesson of the extensive fire of the seventies, has formulated NEC
(nec), clear stipulaties use cmp at plenum space (airspace below ceiling interlayer and raised floor in building)
Fire-retardant communication cable.In Europe, fire safety is increasingly taken seriously, and is also just being equivalent to the data cable standard of cmp grade
In formulation.Propose fire-retardant cmp's in China, GB " integration laying line system engineering design specification " gb50311 2007
Application, open safety, environmental protection, fireproof cable has become a developing direction of current high class data communication cable.
Cmp cable also has using of correlation to specify, the scope that it uses is wider in gb50174, and such as fire-protection rating requires
Higher data center, media center, financial center, conference and exhibition center, hospital, school, museum, the building of high-rise set
There is the cabling requirement of cmp cable, especially in the U.S., Canada, the state such as Britain uses in a large number during meter planning, and in the U.S.
Some occasions specified force use.Purpose is the use of the cable of the cmp grade fire safety grade to improve building, that is,
The flame propagation because cable occurs and the fire producing a large amount of smog and causing largely can be avoided when fire occurs
Accident, thus support personnel smoothly evacuates and escapes.At home, traditional consider from architectural electricity specialty, usually all adopt
Connected up with the mode of poling groove, but increasing case proves, relies on merely the fire prevention of poling mode unreliable, very great Cheng
Still need to ensure from the fire line of cable itself on degree, and regulation machine room is using open in gb 50174 national standard
The method of wiring, puts forward higher requirement to the fire resistance of cable itself, this is accomplished by high fire-retardance etc. in this way
Level material is ensureing this kind of fireproofing of cable performance.And this material relies primarily on external import at present, the present invention just develops
