4.0mm。
This utility model can efficiently solve the solution of problem waterproof, moistureproof:
(1) waterproof, the most moistureproof: 1. during aluminium alloy conductor is stranded, to utilize Electrostatic Spray Technology to make water-proofing powder
Preferably it is attached between conductor single line, the outer wrapped semiconductor waterstop of conductor.2. the gap of insulated wire cores stranding uses and blocks water
Yarn is filled, the outer wrapped semiconductor waterstop of cable core.
(2) the most waterproof, moistureproof: 1. conductor is outer, insulation shielding is outer, the outer wrapped semiconductor waterstop of cable core.2. cable core bag
Outer layer of polyethylene (there is the water resistance of the excellence) separation sleeve that extrudes of band, the outer lock armo aluminum alloy strip of separation sleeve, armor
Extrude outward outer protective polyethylene set.Omnibearing waterproof, humidity resistance has been reached above from longitudinal direction, radially two kinds of structures.Effectively
Solve the water tree and electric branch caused that make moist because of cable or soak, improve service life and the reliability of cable.
In view of XLPE cable water inlet, make moist after impact on cable operational reliability Yu life-span, have been developed over both at home and abroad
Many cables block water technology.These technology that block water generally can be classified as follows: 1. presses used material water-proof material, can be divided into
The technology that actively blocks water and the technology that passively blocks water；2. by the mechanism that blocks water used, longitudinal water-blocking technology and radial water-resisting can be divided into
Technology.Abroad to the research of water repellent electric cable mechanical development relatively early.
Being added by vertical alclad plastic composite strip and extrude low smoke and zero halogen composite sheath, vertical bag is completed by the equipment heated baking of specialty,
The surface film making aluminium-plastic tape lap is bonded, and forms a complete seamless aluminium-plastic pipe, squeezes
During bag low smoke and zero halogen sheath, due to the effect of low smoke and zero halogen sheath melt body height moderate pressure, the low cigarette of plastic-aluminum combined belt surface without
The inner surface of halogen sheath thin film and pe sheath is well pasted, and lap when aluminum plastic belt indulges bag simultaneously also enters one
Step is bondd, thus completely plugged moisture (gas) penetrates into the approach of cable, reaches good radial water-resisting requirement.
The beneficial effects of the utility model:
1. this utility model uses multilayer screen layer the most effectively to ensure the transmission of signal, prevents because power cable contains height
Subharmonic, on cable louding circuit, can produce strong interference to other electronic equipment about, automatically processing device,
To such an extent as to equipment produces misoperation and causes consequence.
2. this utility model is using high density polyethylene (HDPE) sheath as the protection device of whole cable, protects its internal structure to exempt from
Injured by external mechanical force collision, friction etc., it is ensured that the permanently effective operation of cable.
3. this utility model innovatively arranges groove and raised line in internal structure, the two with the use of, it is possible to prevent cable
In use cause the secondary rotating of internal structure, make cable the most stranded, cause damaging.
4. the material of this utility model armor originally uses aluminium alloy, utilizes the advanced technologies of chain armouring, not only may be used
To improve machine security and electrical safety performance, the loss of minimizing circuit of traditional cable, and may also operate as certain resistance
Water and flame retardant effect.Aluminum alloy strip is nonmagnetic substance, even if there is three phase unbalance current, also will not produce eddy current, it is possible to
Reduce the loss of circuit.And once run into fire, the insulated wire cores of inside can be made well to isolate with outside burning things which may cause a fire disaster, play one
Fixed flame retardant effect.Further, since armor is self-locking form, sealing is preferable, has certain radial water-resisting performance.
