High speed development, increases day by day to extraordinary high-end cabling requirements, and copper resource is the most in short supply, and major part is leaned on
Import, consumes substantial amounts of valuable foreign exchange reserve.Copper valency undulation remains high for many years so that electricity
Cable cost increases profit and reduces, and China is aluminum great industry nation, the most domestic shape being in production capacity surplus
State.In the case, we pass through technology exploration, endeavour to develop the aluminium alloy of great market prospect
Carry chain armouring inorganic mineral insulation fireproof cable (BTLY).
Utility model content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of aluminum alloy strip
Chain armouring inorganic mineral BTLY insulated cable.
This utility model alloy strip chain armouring inorganic mineral BTLY insulated cable, it comprises naked copper and leads
Body 1, fire-resistant isinglass belt 2, fire proofing firbre band 3, implant 4, flame retardant insulation 5, aluminium alloy are even
Lock armor 6, inorganic mineral band 7 and low smoke and zero halogen sheath 8, bare copper conductor 1 includes three masters
Core line, two neutral conductors, the outside of bare copper conductor 1 around double-bag fire-resistant isinglass belt 2 as every
Oxygen layer, the outside wrapped fire proofing firbre band 3 of fire-resistant isinglass belt 2 is as insulating barrier, fire proofing firbre band 3
The wrapped flame retardant insulation in outside 5, be filled with implant 4 between many bare copper conductors 1, many naked
The outside of copper conductor 1 is surrounded with the chain armor of aluminium alloy 6, the outside of the chain armor of aluminium alloy 6
Being surrounded with inorganic mineral band 7, the outside of inorganic mineral band 7 is surrounded with low smoke and zero halogen sheath 8.
As preferably, described implant 4 is that heat insulation and that flameproof effect is all good inorganic fire is filled
Thing, this implant has the features such as lightweight, easy-formation, uses this structure all can ensure electricity
The rounding of cable and pliability.
As preferably, the self-locking armouring of described aluminium alloy chain armor 6 uniqueness, there is intensity
Height, pliability are good, the features such as bending radius is little, non magnetic.
As preferably, described inorganic mineral band 7 wraps up through band, further increases cable
The rounding property of structure and fire insulation.
Preferably, low smoke and zero halogen sheath 8 uses low smoke and zero halogen crosslinked polyolefin materials to make, this
Material is by, after high energy electron ray cross-linking radiation, being greatly improved the physics of cable, mechanicalness
Can, it is effectively improved the protection intensity to wire, makes cable have resistance to compression, ageing-resistant, acid and alkali-resistance ring
Border, salt spray resistance, the good performance such as waterproof, be suitable for using in different environments, and safety is reliable,
Ageing resistace is long for good service life.
The beneficial effects of the utility model: 1, fire prevention, fire resistance the most superior, for ensureing at fire
Energy normal power supply in flame, i.e. keeps the construction of cable stable under conditions of catching fire, sets at the construction of cable
Adding one layer in meter and have inorganic mineral clad that is fire-resistant and that have expansion character, this clad exists
Under flame condition, volumetric expansion makes cable insulation structure more stable.Therefore this cable can connect
Continue to keep power supply under the fire condition of nearly logical fusing point, be a kind of fireproof cable truly.
2, produce continuously, cross section is big, good bending property, and the production length of this cable is not by processing work
Skill, the restriction of production equipment, fully meet for electrical length needs, and this cable conductor uses multiply list
Line is stranded to be formed, and do so largely can increase the flexibility of conductor, additionally stranded conductor
Continuous production is good, and processing length is big, can reduce the quantity of joint, big single-core cable cross section, cross section
Up to 800MM2；The chain armoured process of aluminum alloy strip, adds the flexibility of cable, bending property
Good.
3, current-carrying capacity is big, waterproof, and when this cable is normal, conductor temperature can reach 180 DEG C, in phase
On the premise of conductor boundary, its magnitude of current is considerably beyond normal cable；This cable uses and seals magnetic
Property aluminum pipe protection, its water resistance is superior.
4, there is explosion-proof, anticorrosion, without emi characteristics, owing to this cable uses aluminum alloy strip even
Lock armouring, and cable is after burning, and packed layer produces tightly compacted core after expanding, flammable
Gas, flame can not reach the electrical equipment being connected with cable, and therefore cable has explosion-resistance characteristic,
Supplementary protection is need not, under special environmental condition, as aluminum is had in the environment of normal use
In the environment of stronger corrosiveness, it is only necessary to add one layer of low smoke and zero halogen sheath outside cable and just may be used
To reach anticorrosive property；This cable due under the shielding of aluminium sheath, with the line such as information, control
When laying together, signal, control line will not be produced interference.
