Description

Fire prevention aluminium core composite cable

Technical field

The utility model relates to the optical cable technology field, definite says that it is a kind of fire prevention aluminium core composite cable with fire prevention, heat-resisting, fire resistance.

Background technology

At present, in Communication in China, computerized information industrial field, the optoelectronic composite cable with broadband data transmission and function of supplying power is widely used in the communication equipment remote electric power system.And because China's fire disaster constantly takes place, cause great harm for people's productive life recent years.Electricity consumption and security against fire receive much attention during the acceptance of work, if transmit electricity cable not tool fire prevention or fire resistance in the engineering, will become the major hidden danger of fire in actual use, mainly are because the transmission of electricity cable is in use once produce the high heat of high temperature after the overload.The insulating barrier of common cable can produce naked light in this case, and possibly cause the naked light rapid spread, causes the generation of fire thus.Secondly be exactly when fire takes place, common cable insulating barrier is met naked light can enlarge the fire damage scope with fire spreading.Therefore some important engineering has explicitly called for and must adopt fire-resistant, flame-retardant cable access; The part engineering causes doing over again owing to the electricity consumption fire-fighting is defective and reprocesses, even the shut-down of whole engineering is rectified;

This shows that each engineering must guarantee security against fire when implementing, is prerequisite to guarantee the safety of the people's lies and property; Therefore no matter be in the remote electric power system of communications industry field, still in unification of three nets in the future or four networks one platform network, use the fire prevention optoelectronic composite cable to have higher certainty; Can improve fail safe, the stability of light engineering cable after this technical application to a great extent, prolong the useful life of optoelectronic composite cable simultaneously, the people's lives and property safety is protected.

But because recent years, copper material soared all the way, bring very big pressure for the cables manufacturing industry, the rise significantly of cable price causes and makes a part of user to accept, even produces economic dispute, delayed works; The manufacturer of small scale stops production one after another, and producer that can ordinary production also has leans on the minimizing raw material to adulterate to keep price competition, caused very big hidden danger of quality to application unit greatly.Use aluminum steel replacement copper cash, can practice thrift cost to a great extent.

Summary of the invention

The purpose of the utility model provides a kind of fire prevention aluminium core composite cable with fire prevention, heat-resisting, fire resistance.The technical scheme of the utility model is: it comprises sheath, aluminum steel bed course, aluminum conductor, cable core filled composite, reinforcement bed course, reinforcement, optical fiber, pine cover filled composite, loose sleeve pipe, moisture-proof layer; It is characterized in that: loose sleeve pipe and aluminum conductor are stranded round reinforcement; They have optical fiber and pine cover filled composite in the loose sleeve pipe in band, aluminum conductor is outward the aluminum conductor bed course; Band is outward a moisture-proof layer, and moisture-proof layer is outward a sheath.Also has gasket for packing round reinforcement in the band.Prick yarn, inner cushion layer and nonmetal auxiliary stiffener in the band in addition.Reinforcement has the reinforcement bed course outward.

The utility model has the advantages that:

1, fire-resistant, high temperature resistant, the tool fire protecting performance; The operating state that still can keep normal power supply with the naked light burning more than 4 hours;

2, have fire resistance, can stop or delay fire spreading with the naked light combustion;

Have more fail safe when 3, burning, the smog light transmittance is high during burning, and does not contain halogen element in the smog;

The serial problem that 4, generally could solve with many cables can replace with a composite rope at this;

5, can satisfy long Distance Transmission, also sectional uses;

6, the physical characteristic that still keeps optical cable is like anti-collapse, stretching etc.;

7, client's purchase cost is low, and operating expenses is low, and the networking expense is low;

8, have superior bending property and good anti-side pressure performance, easy construction;

9, multiple transmission technology is provided simultaneously, strong with adaptability height, the extensibility of equipment, product is widely applicable;

10, provide huge bandwidth to insert, guarantee the remote power feeding demand;

11, practice thrift cost, optical fiber as the usefulness of reserving to the family, has been avoided the secondary wiring;

12, solve equipment electrical problem (avoiding repeating to lay supply line) in the networking;

13, according to ports such as customer requirement FC/SC/ST.
