3rd, provided with double-deck mineral insulation, plus inorganic thermal insulation fireprotection layer so that cable has fire-proof insulation from inside to outside, obtains
Multiple flameproof protection is arrived；And formed using Environmental-protective fire-proof nanometer mineral insulation material, under rated voltage can 2.5 times of excess load and
As usual insulating effect is played；Long-term service temperature scope is：- 40 degrees Celsius to 1200 degrees Celsius, insulate as usual；800-
It is not short-circuit in 1.5 hours under the ablation of 1200 degrees Celsius of naked lights, do not trigger electric fire, more will not be combustion-supporting；In naked light ablation process
In, not only fire retardant nonflame, and no longer release asphyxia toxic gas, there is low cigarette, nontoxic, Halogen, fire-retardant characteristic；Bearing
During mechanical external force, electromagnetism interference；Cost is low, good performance indexes；It is suitable for the insulating barrier of various electric wires.
4th, the present invention winds glass fabric in steel band shielding and copper strip shielding, and individually all screen layer has been fire prevention guarantor
Shield so that the shield effectiveness of cable is more preferable；
5th, provided with double-level-metal screen layer, strengthen effect of the limitation electric field in insulating barrier, make direction of an electric field and insulation radius side
To consistent（I.e. radially）, metallic shield is with ground, and electric field is terminated on metal tape, and metal tape is outer, and there is no electric field.Prevent axial direction
Surface-discharge, cable, because semi-conductive layer has certain resistance coefficient, axially may be used in the environment of no good earth in cable
Potential distribution can be caused uneven, cause cable creeping discharge.In addition, capacitance current is flowed through under normal circumstances, metal when short-circuit
Band can improve metal screen layer capacitance current and short circuit current transmittability and anti-electromagnetism done as the loop of short-circuit current
Disturb, be homogenized the ability of electric field.
6th, interior to be externally provided with Zero halogen flame resistance polyethylene braid over braid and double-deck fire prevention band, band is wound in unit cable appearance,
It can expand to form charing body rapidly during flame contact, prevent flame ignition cable so that cable environmental protection, Halogen in burning, more
Add safety.
7th, the cable changes the design of sheath, is designed using shell-less, uses non-woven fabric compounded aluminium foil high temperature resistant heat insulation
Reflecting layer so that cable barrier property is superior, and moisture-proof heat-preservation performance is good, and thermal conductivity factor is low, and thermal resistivity R values are high, and reflectivity is high, together
When also obstruct the heat in the external world, instead of restrictive coating, alleviate the weight of cable.
8th, in the second mineral insulation, steel band screen layer, copper strip shielding layer and non-woven fabric compounded aluminium foil high temperature resistant heat insulation
The outer surface in reflecting layer scribbles fireproof coating layer, and not only causing every layer all serves fireproof protecting effect, also greatly improves
The overall flameproof effect of cable.
