电缆的阻燃性能符合国家标准GB 12666.5的要求。
耐火BV线在导体和绝缘层之间有一层耐火云母带，耐火BV线在着火的时候仍然可以正常使用一段时间啊，电缆缆的耐火性符合国家标准GB 12666.6的要求。
以变压器接线方式Y/△11为例，讲解星转角（Y△）问题：1.1为了便于理解本文假设：变压器高低压侧额定电流均为1A；变压器平衡系数为1；从相量图我们可以看到两侧电流之间会出现30的相位差，那怎么干掉这30°的相位差呢？当然是要通过保护装置的软件算法对相位进行校正。
微机型保护装置有2种相位校正方式：三角形侧向星形侧校正（△Y）和星形侧向三角形侧校正（Y△）。

我国广泛采用的是星形侧向三角形侧校正（Y△）方式，本文也只讲解星形侧向三角形侧校正（Y△）这种方式。

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 requirements of the basic cable. 6. Cable length: mechanically protected cable is made according to the length of the corresponding basic cable

同样的道理，如果有屏蔽线起到屏蔽作用的话，外部干扰源对于其的干扰影响也可以尽可能的缩小。
3.选择使用普通的超五类屏蔽双绞线即网线就可以。
由于原材料价格上涨，导致现在市场上的线材鱼龙混杂，有不良商人利用某种合金来顶替铜丝来做网线，在外面镀铜以蒙混客户。
