It is transferred to the wire at another place.Cable has interior energization, the feature of external insulation.Cable has power cable, control cable, compensation electricity
Cable, shielded cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resisting cable, cable for ship, mine cable,
Aluminium alloy cable etc..They are all made up of sub-thread or stranded conductor and insulating barrier, for connecting circuit and electrical equipment etc..It is existing
Crosslinked polyetylene insulated layer steel-tape armouring pe sheath electric power suitable for 21/35kv electric line system make match somebody with somebody power transmission
It can be used.The electrical power trans mission/distribution system is divided into two classes according to national standard.One kind refers to any phase conductor of the system and ground or ground connection
When conductor contacts, it can be separated in one minute with system, one kind refers to that the system includes the bar that singlephase earth fault is run in short-term
Part, the earth fault time should be no more than 1 hour, but under any circumstance, no longer than 8 hours, annual earth fault was always held
The continuous time is no more than 125 hours.
Existing cable, the requirement of high resiliency, high abrasion can be met, but the interference in the external world can not be resisted, and two
Also exist between and interfere.In order to anti-tampering, some cables are adjusted in structure, and screen has been woven after insulating core stranding
Cover, finally squeeze elastic body jacket, not only overall dimensions are big for this structure, and the interference between core pair is still present, some cables pair
Each pair weaves split screen, and total screen has been woven again after split screen, but physical dimension is huge, weight penalty, and elasticity is poor with bendability, it is impossible to
Meet the laying of small space.Rated temperature during work is not up to standard, and pollutes environment, and security performance is low, easy aging, leads
Poor electrical performance.
Therefore, in order to adapt to the requirement in market, the strength and occupation rate of market of enterprise itself is improved, develops novel aluminum
Crosslinked polyetylene insulated nonmagnetic metal band armored cable is pressed in core.
