Abstract
A kind of multicore fireproof power cable, relates to the manufacturing technology field of power cable.The utility model comprises cable core, sets gradually Ceramic silicon rubber band lapping layer, Ceramic silicon rubber inner covering, steel-tape armouring layer and flame-retardant low-smoke halogen-free polyolefin external sheath layer outside cable core; It is circular insulated electric conductor that cable core comprises a cross section, is that to set gradually many cross sections be fan-shaped insulated electric conductor for the periphery of circular insulated electric conductor along cross section; Cross section is that circular insulated electric conductor comprises the first copper conductor, at the first copper conductor arranged outside first Ceramic silicon rubber insulating barrier; Every root cross section is that fan-shaped insulated electric conductor comprises the second copper conductor respectively, at the second copper conductor arranged outside second Ceramic silicon rubber insulating barrier.Cable core is designed to 5 or 6 and fan-shapedly synthesizes a great circle round circular group by the utility model, and segment conductor-core arranges that forming loop configuration makes compact strong, promotes overall resistance to mechanical intensity, greatly reduces the cost of product.
Description
Technical field
The utility model relates to the manufacturing technology field of power cable.
Background technology
Power cable is divided into some kinds by principal characters such as its usage range, design feature and performance requirements, along with the growth of Chinese national economy, various heavy construction is inevitable with power cable as main line, but according to the demand of different occasion, also different to cable needs.
Utility model content
The utility model object is for above problem, provides a kind of multicore fireproof power cable of meeting the market requirement.
The utility model comprises cable core, sets gradually Ceramic silicon rubber band lapping layer, Ceramic silicon rubber inner covering, steel-tape armouring layer and flame-retardant low-smoke halogen-free polyolefin external sheath layer outside described cable core; It is circular insulated electric conductor that described cable core comprises a cross section, is that to set gradually at least five cross sections be fan-shaped insulated electric conductor for the periphery of circular insulated electric conductor along cross section; Described cross section is that circular insulated electric conductor comprises the first copper conductor, at described first copper conductor arranged outside first Ceramic silicon rubber insulating barrier; Cross section described in every root is that fan-shaped insulated electric conductor comprises the second copper conductor respectively, at described second copper conductor arranged outside second Ceramic silicon rubber insulating barrier.
The utility model 650 DEG C ~ 3000 DEG C have flame or nonflame condition under can form the insulation shell of ceramic-like, keep the integrality of circuit, realize the continuous transmission of electric energy.Residue simultaneously after its burning is ceramic-like duricrust, duricrust not melting under fire (650 ~ 1300 DEG C) environment, does not drip, and ensures that electric power, communication are in case of fire unimpeded, plays firm protective effect.The A grade standard that cable fire grade can reach GB12666.6 (burns 90 minutes in 950 DEG C ~ 1000 DEG C flame, 3A fuse does not fuse), also test by the CWZ highest level of Britain BS6387 that (C---burns 3 hours in 950 DEG C of flame; W---Water spray; Z---shakes).Flue gas after burning---low cigarette, Halogen, without phosphorus nitrogen, heavy metal free, nontoxic, harmless, flue gas toxity level of security reach macromolecular material the highest level of security ZA1 level (animal used as test within 30 minutes contamination phases and after in 3 days not dead and average weight recover), can not secondary injury be caused to people.The utility model architecture advances is ingenious, cable core is designed to 5 or 6 sector structures and a circular configuration, 5 or 6 fan-shaped synthesizes a great circle round circular group, segment conductor-core is arranged symmetrically with formation loop configuration and makes compact strong, thus promote overall resistance to mechanical intensity, make the structure of cable product compacter, also greatly reduce the cost of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises cable core 1, sets gradually Ceramic silicon rubber band lapping layer 2, Ceramic silicon rubber inner covering 3, steel-tape armouring layer 4 and flame-retardant low-smoke halogen-free polyolefin external sheath layer 5 outside cable core 1; It is circular insulated electric conductor 6 that cable core 1 comprises a cross section, is that to set gradually six roots of sensation cross section be fan-shaped insulated electric conductor 7 for the periphery of circular insulated electric conductor 6 along cross section; Cross section is that circular insulated electric conductor 6 comprises the first copper conductor 8, at the first copper conductor 8 arranged outside first Ceramic silicon rubber insulating barrier 9; Every root cross section is that fan-shaped insulated electric conductor 7 comprises the second copper conductor 10 respectively, at the second copper conductor 10 arranged outside second Ceramic silicon rubber insulating barrier 11.
