三相五线制是我国电气技术中一个错误的名词,根据《供配电系统设计规范》GB50052-2009第7.0.1条将低压配电系统分成了两类,一类是按照配电系统中的相数和带电导体数进行的分类,即带电导体系统;另一类是按照低压配电系统的接地型式。有些人员认为三相五线制比三相四相四线制多了一个PE线,三个相线加一个中性线再加一个PE线,所以称为三相五线制。PE线是为了保护人身安全设立的保护接地导体,在正常情况下PE线是不电的。

可根据用户要求将多根信号线、电源线、屏蔽线、同轴射频电缆等组合成一根可带总屏蔽的组合电缆。另外我厂新研制开发出自承式组合电缆在SYV75-5+RVV+RVVP电缆基础上,电缆另加一根自承式钢丝,使电缆拉力大大增强。
Armoured communication cable armoring cable type: HYA53, HYAT53, HYA23 HYAT23, HYV22, HYA22 (rat, buried) armoring communication cable USES: armoured communication cable mechanical protective layer can be appended to the structure of the cable, with the mechanical strength of the cable, antierosion capability, is vulnerable to mechanical and designed and vulnerable to erosion area telephone cable. Any kind of laying can be adopted, which is more suitable for direct buried laying in rock area. Armored communication cable structure: 1. Basic cable: any filled and unfilled cable with single sheath or double sheath structure. 2. Armored communication cable mechanical protection layer: type 53 adopts 0.15mm thick corrugated steel belt, which is longitudinal wrapped on the basic cable and overlapped on both sides. The surface of the steel belt is coated with plastic to prevent corrosion and water intrusion. The type 23,22 has similar performance with double steel band wrapping. 3. Armored communication cable sheath: black high-molecular weight low-density polyurethane or polyurethane sheath. Sheath thickness may depend on the basic cable outer diameter. 5. The marking contents of armored communication cables include: wire diameter, number of wire pairs, cable model, length, manufacturer name and year of manufacture. 6. Armored communication cable electrical characteristics: the cable meets all the electrical re of the basic cable. 6. Cable length: mechanically protected cable is made according to the length of the corresponding basic cable
不过我们家庭使用,看重的是电线载流量高、延展性强、抗机械能力强等。因此适合家用的电线,非铜制电线莫属了。型号解读在型号方面,家用常常使用四种:BV线,BVR线,BVV线和BVVR线。此外,还有四种也会出现在我们的日常生活中,不过在家庭装修时使用的比较少,分别是RVV、BVVBVVRB和RVVB线。这八种电线的型号中,BV线和BVR线不能直接暴露在空气中,也不能直接与墙壁、地面接触,使用时需要搭配穿线管或线槽;其余四种又可叫做“护套线”,可直接暴露在空气中使用(可以使用线卡子固定,亦可使用线槽或穿线管),但不能直接深埋在地下或墙面内(只有铠装电线可以直接埋,不过家庭没必要使用,将来维修还是个麻烦事)。
