接地线选用黄绿双色线，接开关线选用红、黄、蓝、绿、黑等任一种。2000年后，电路设计一般是：进户线6—10mm2，照明2.5mm2，插座4mm2，空调6mm2专线。单芯电线1.5平方电线，用于灯具照明，单芯电线2.5平方电线，用于插座。
Purpose of HYAT solid insulated filled cable: solid insulated filled cable is suitable for the urban telecommunication line of the local telecommunication network in the town of wuyu, and also for the special network line connecting to the public network. Mainly used for pipeline laying. The inner and outer surfaces of the cable core and the shield layer are filled with oil paste and poured to prevent water intrusion. The mechanical and electrical properties of the cable remain unchanged under conditions of 30~C - 60~C. Structure: wire: annealed bare copper wire, copper wire diameter 0. 32, 0. 40, 0. 50, 0. 60, 0. 70, 0. 80, 0. 90 (mm). Insulating material: high density polypropylene or polypropylene, colour of the insulated wire as indicated by full chromatograph. Pair of insulated wires: twist two different colored insulated wires into pairs at different pitch and use the specified chromatographic combination to identify pairs. Core structure: with 25 pairs as the basic unit, more than 25 pairs of cables are assembled according to the unit, each unit is wired with the unit of specified chromatogram to identify different units. 100 pairs of cables with more than one pair of cables plus 1% of the reserve pair, but not more than 6 pairs. The gap in the core is filled with oil paste. Core tape: wrap with a polygrease film tape. Shielding: metal strip with or without striping, which is longitudinal wrapped outside the core of the cable. Sheath: black low density polymer. Double sheathed cables can also be provided. Identification and marking: cable outer surface sexual identification mark, mark at no more than alternate 1 m intervals, tag contents are: the diameter of wire, line number, cable type, factory name and year of manufacture, marking at no more than alternate 1 m intervals to mark on the surface, but with the tag stagger. Other structures: according to the needs of users, we can provide armored cables HYAT53, HYAT55 and high frequency isolation cables YATG with strengthened mechanical protection layer.

In flame retardant series products, has been successfully used in the oxygen isolation technology, not only 0.6/1 kv polyvinyl chloride insulated and crosslinked polyethylene insulation flame retardant power cable can achieve GB/T12666.5 "into A bunch of power cable test" in class A, and rated voltage up to and including 6/10 kv 6/10 kv crosslinked poly (flame retardant power cable can reach A high class A demand and A large margin. On the basis of high flame retardant and high flame retardant cross-linked insulation, a low-smoke halogen-free high-flame retardant oxygen insulation layer power cable was added, and its low-smoke halogen-free performance was in line with GB/T17651.1.2 and GB/ t1765650.1.2. In this way, the overall level of the company's cross-linked power cable is lower than the domestic status.

2015年4月，某电站全停电恢复送电时，在对220kV#2主变充电时，#2主变高压侧202断路器合闸，由于#2主变空充产生了很大的励磁涌流，#1发电机系统也因此产生了和应涌流，由于涌流中含有较大的非周期分量，从而使进入#1发电机两套保护装置电流均发生了畸变。因发电机机端及中性点使用的CT不是同一厂家生产，CT的传变特性存在差异，饱和程度也不一致，发电机机端和发电机中性点的电流畸变程度不一致，造成发电机差动回路出现差流，引起#1发电机(正常运行的)主二套保护装置发电机比率差动保护动作，#1发电机出口011断路器跳闸。
