The product is used for rated voltage of 3.6 (6) / 6 kV, 6.0 (8.7) / 10 kV, 8.7 (12) / 15 kV, 12 (18) / 20 kV, 21 (26) / 35 kV power distribution system, for transmission and distribution of electric energy use.

二、执行标准 Standards

本产品按照等效采用IEC 60502标准的GB/T 12706标准进行生产，阻燃类电缆符合国标GB/T 19666。

This product is used in ordance with IEC 60502 standard is equivalent to GB / T 12706 standard for production. Flame-retardant cable meets the national standard GB / T 19666.

三、使用特性 Product features

1、电缆导体最高允许工作温度：正常运行时90 ℃，短路时（最长5 s）为250 ℃。

Max. admissible temperature for conductor：90 ℃ under normal running condition，250 ℃ during short circuit（max. duration not exceeding 5s）.

2、U0按系统接地故障持续时间不同分为两类，见表3-1

第1类电缆——用于单相接地故障时间每次不大于1分钟的系统，亦可用于最长不超过8 h，每年累计不超过125 h的系统。

第2类电缆——用于接地故障时间更长的系统，对电缆绝缘性能要求较高的场合，也应采用第2类。

U0ording to system ground fault duration pided into two categories, see Table 3-1.

Class 1 cable -- time for single-phase ground fault is less than 1 minute each time the system can be used for no longer than 8 h, 125 h per year does not exceed the total system.

Category 2 cable -- longer for ground-fault system, the cable insulation applications requiring high performance, it should be Category 2.

3、电缆在环境温度不低于0 ℃条件下敷设时，无须预先加热，电缆的敷设不受落差限制。敷设时最0.小弯曲半径：

Cable of not less than 0 ℃ ambient temperature under the conditions of laying, without pre-heating, cable laying is not drop restrictions. Minimum bending radius when laid:

单芯电缆（Single-core cable） 20（D+d）±5%mm

多芯电缆（Multi-core cable） 15（D+d）±5%mm

式中（Where）：D——电缆的实际外径（The actual diameter of the cable），mm

d——电缆导体的实际外径（The actual diameter of the cable conductor），mm

七、交货长度  Delivery length

电缆交货长度一般不少于100米。

允许短于50米的短段电缆交货，但其数量应不超过交货总量的10%，允许交货长度有±0.5%的误差。

具体交货长度由供需双方商定。

Cable delivery length is generally less than 100 meters.

Allowing less than 50 meters short section of cable delivery, but their number should not exceed 10% of total delivery, delivery length to allow error ± 0.5%.

The specific length of delivery agreed upon by both parties.

八、订货须知  Ordering Information

定货时需注明电缆的额定电压、型号或名称、规格、长度、所执行的标准。

如：要定8.7/10KV三芯铜芯240mm2钢带铠装的交联聚乙烯绝缘、聚氯乙烯护套电力电缆10公里，应写成：8.7/10KV YJV22 3×240mm2 10KM GB/T12706-2002

定货时请注意：交联聚乙烯绝缘电缆应选择专用的交联聚乙烯电缆终端和连接头配套使用。

Orders must be marked when the cable’s rated voltage, model number or name, size, length, the implementation of the standards.

Such as: To set 8.7/10KV three-core copper, steel tape armored 240mm2 XLPE insulated, PVC sheathed power cable 10 km should be written as: 8.7/10KV YJV22 3 × 240mm2 10KM GB/T12706-2002.

When ordering, please note: cross-linked polyethylene insulated cables should choose a dedicated cross-linked polyethylene cables supporting the use of terminals and connectors
