Description
Technical field
This utility model is related to power cable, especially environmental-friendly halogen-free low-smoke polyolefin medium-pressure power cable.
Background technology
With the gradual perfection that modern urbanization is built, various cables are applied to down town, are particularly some populations
Intensive place, such as market, hospital, school etc..And cable is responsible for the functions such as the transmission of electric energy, due to densely populated place
Flow of the people is big, environment closing, causes the factor of fire especially many, and general cable can discharge when there is fire burning and substantial amounts of have
Poisonous gas and flue dust, are unfavorable for the evacuation of crowd.In the market also not for the exploitation of densely populated place with environmental protection
Excellent performance, the medium-pressure power cable that flue dust is few, light transmittance is high produced when discharging without harmful gass during burning, and burning.
The content of the invention
The purpose of this utility model is aiming at disadvantage mentioned above and is improved, there is provided a kind of to make simple, during cable fire
The environmental-friendly halogen-free low-smoke polyolefin medium voltage electricity that flue dust is few, light transmittance the is high electricity produced when discharging without harmful gass, and burning
Cable.
This utility model environmental-friendly halogen-free low-smoke polyolefin medium-pressure power cable, it is characterised in that：Including by three conductors
The cable core of composition, every conductor are coated with conductor shield, insulating barrier, insulation screen and metallic shield from the inside to the outside successively
Layer, the cable core are coated with lapping layer, inner sheath, armor and outer jacket from inside to outside successively, the cable core with it is wrapped
Space between layer is provided with implant.
The metal screen layer adopts copper strip shielding, and copper strips is wrapped using single overlays, averagely puts up rate not little between copper strips
In 20%.
The implant is filled using mineral wool rope.
The lapping layer is carried out wrapped using LSOH anti-flaming glass cloth twining package tape.
The sheath adopts black linear low density polyethylene protective cover material.
The armor is wrapped using galvanized steel strip Double-layer gap, and steel band gap is not more than the 50% of width of steel band.
The outer jacket adopts halogen-free and low-smoke flame-retardant polyolefin sheathed material.
This utility model makes simple, and the flue dust produced when discharging without harmful gass during cable fire, and burning is few, printing opacity
Rate is high, meets environmental requirement.
Description of the drawings
Fig. 1 is this utility model structural representation.
In figure：1- conductors, 2- conductor shields, 3- insulating barriers, 4- insulation screens, 5- metal screen layers, 6- lapping layers,

Specific embodiment
Referring to Fig. 1, this utility model environmental-friendly halogen-free low-smoke polyolefin medium-pressure power cable, including by three 1 structures of conductor
Into cable core, every conductor is coated with conductor shield 2, insulating barrier 3, insulation screen 4 and metal screen from the inside to the outside successively
Layer 5 is covered, the cable core is coated with lapping layer 6, inner sheath 7, armor 8 and outer jacket 9, the cable core from inside to outside successively
Space between lapping layer is provided with implant 10；The metal screen layer adopts copper strip shielding, copper strips using single overlays around
Bag, averagely puts up rate not less than 20% between copper strips, shielding propertiess are good；The implant is filled using mineral wool rope, allows cable more
Rounding and environmental protection；The lapping layer is carried out wrapped using LSOH anti-flaming glass cloth twining package tape；The sheath adopts black
Linear low density polyethylene protective cover material；The armor is wrapped using galvanized steel strip Double-layer gap, and steel band gap is not more than steel band
The 50% of width, plays protection cable effect well；The outer jacket adopts halogen-free and low-smoke flame-retardant polyolefin sheathed material, oxygen to refer to
Number is high, not halogen-containing in sheath material, and the flue dust produced when discharging without harmful gass during burning, and burning is less, and light transmittance is high,
Meet environmental requirement.
