Abstract
The utility model provides a double non-magnetic metal power cable with an armored termite-proof sheath. The power cable comprises an outer sheath, an armor layer, a spacing sleeve, an inner protecting layer, a copper strip shield layer, an insulating shield layer, an insulating layer, a conductor shield layer and a conductor cable core, which are coaxially connected from outside to inside. The utility model has the technical benefits as follows: the power cable has the advantages of high current-carrying capacity, good demagnetizing effect and high safety and reliability, is applicable to the power transmission lines of the first-level load and the general load with strict requirement of power supply reliability, and is applicable to the place requiring protection against termites and mice and the humid place as well.
Description
Technical field
The utility model relates to a kind of power cable, relates in particular to the power cable of a kind of pair of termite-proof sheath of nonmagnetic metal band armouring.
Background technology
Cable is normally by the single or stranded similar funicular conductor thread core that forms of multiple conducting wires, extruded insulation outside conductor thread core, and whole outside is surrounded by the cover layer (being protective coverings of cable) of height barrier propterty.Cable is because Heavy Weight, and length is long, and set up in inconvenient high-altitude, so that cable all is laid on usually is underground.Though be laid on underground convenience, the laying expense is few, is convenient to safeguard, because that cable is laid on for a long time is underground, is subjected to termite to sting erosion easily, and is very big to cable destruction.
Summary of the invention
The purpose of this utility model has been to provide the power cable of a kind of pair of termite-proof sheath of nonmagnetic metal band armouring, and this power cable has solved cable is stung erosion by termite problem.
The utility model is achieved like this, it comprises oversheath, armour, separation sleeve, sheath, copper strips screen, insulation screen, insulating barrier, conductor shield, conductor thread core, it is characterized in that coaxial successively from outside to inside connection oversheath, armour, separation sleeve, sheath, copper strips screen, insulation screen, insulating barrier, conductor shield and conductor thread core.
Technique effect of the present utility model is: have advantages such as ampacity is big, demagnetization is good, safe and reliable, be applicable to the through track occasion of demanding stage load of power supply reliability and synthetic load; Be applicable to the termite-proof occasion that has anti-rat eaten requirement concurrently; Be applicable to moist place.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is achieved like this, coaxial successively from outside to inside connection oversheath 1, armour 2, separation sleeve 3, sheath 4, copper strips screen 5, insulation screen 6, insulating barrier 7, conductor shield 8 and conductor thread core 9.Adopt nonmagnetic metal band armouring and termite-proof polyethylene or pvc sheaths such as single core, stainless steel band or aluminium strip.The cable conductor core through interior screen, insulation and outside shield three-layer co-extruded after, crosslinked through catenary crosslinking pipe nitrogen, high temp. dry type, making the specified operating temperature of cable conductor is 90 ℃, the maximum temperature of (duration the longest be 5s) cable conductor is 250 ℃ during short circuit.
