1. Conceptes diferents
Cable de blindatge: Està instal·lat per diferents conductors de materials en una funda metàl·lica amb materials aïllants, i es processa en una combinació sòlida de flexió.
Cable sense blindatge: cables sense capes protectores d'armadura, de diversos o diversos jocs de cables en cada grup d'almenys dos cables trenats, cada conjunt de cables aïllat, sovint envolta un centre retorçat. Tot el pa exterior té una capa de cobertura molt aïllada.
2. Different uses
Cable de blindatge: Generally used in the case of ground, the cable trench is laid or buried in direct burial.
Cable sense blindatge: Except for land burial, it is a non-armor cable.
3. The armored cable is wrapped in steel bands or steel wires to protect the cables from being damaged and damaged by external mechanical forces. You can also prevent mice and termites to bite so that the power transmission problem is not caused by the armor. El curved radius of the armor is large, and the armor layer can be ground to protect the cable.
4. The external protective layer of the armored cable is wrapped in steel bands or steel wires to protect the cable from being damaged by external mechanical forces. El cross-linked cable refers to the insulation layer outside the cable conductor is the use of cross-linked polyethylene materials. Armoring cables can be used, which can be used with cross-linking materials and the outer layer of the armor.
5. The method of representing armor cables is on ordinary cables+numbers. The first: “2” indicates double steel band armor; second: “2” means polyvinyl chloride cover, such as polyethylene sheath Change “2” a “3”. Per exemple, YJV represents ordinary cables and YJV22 represents armor cables.
6. Armor cables are generally about 12-15%higher than the price without armor. The cables have good external protection. Per exemple, if the steel tube is protected, or placed in a very good operating environment, from the perspective of the engineering economy, ordinary cables can be used without armor.
