This product is suitable for the signal transmission, control and measurement system of electrical instruments and power distribution devices with AC rated voltage (U0/U) 450/750V and one-time. It can be widely used in various fields such as metallurgy, electric power, petroleum and chemical industry.

使用特性Use characteristics

1、电缆额定电压U0/U:450/750V

Rated cable voltage U0/U: 450/750V

U0-电缆设计用的导体对地域金属屏蔽之间的额定工频电压;

U0-The rated power frequency voltage between the conductor used in the cable design and the regional metal shield

U-电缆设计用的导体间的额定工频电压;

U- rated power frequency voltage between conductors used in cable design;

2、电缆正常运行时导体很高工作温度:交联聚乙烯绝缘为90℃;聚氯乙烯绝缘为70℃。

The maximum working temperature of the conductor during the normal operation of the cable: 90°C for cross-linked polyethylene insulation; 70°C for polyvinyl chloride insulation.

3、电缆短路时导体很高温度:交联聚乙烯绝缘为250℃;聚氯乙烯绝缘为160℃(短路很长持续时间为5秒)。

The maximum temperature of the conductor when the cable is short-circuited: 250°C for cross-linked polyethylene insulation; 160°C for polyvinyl chloride insulation (the longest short-circuit duration is 5 seconds).

4、电缆安装时很小弯曲半径:

Minimum bending radius during cable installation:

有铠装或绕包屏蔽结构的电缆应不小于电缆外径的12倍;

Cables with armored or wrapped shielding structure should not be less than 12 times the outer diameter of the cable;

其余结构电缆应不小于电缆外径的6倍。

Other structural cables should not be less than 6 times the outer diameter of the cable.

5、电缆的很低允许敷设温度:敷设时电缆温度不低于0℃,环境温度低于0℃时,应对电缆进行预热。

The minimum allowable laying temperature of the cable: the temperature of the cable shall not be lower than 0℃ during laying, and the cable should be preheated when the ambient temperature is lower than 0℃.

6、电缆绝缘电阻:很高额定温度时。体积电阻率r不低于1012Ω.cm;绝缘电阻常数Ki不小于36.7MΩ.km。Cable insulation resistance: at the highest rated temperature. The volume resistivity r is not less than 1012Ω.cm; the insulation resistance constant Ki is not less than 36.7MΩ.km.
