二、主要技术特点

  

II. Major technical characteristics

  

本产品仅含少量的有机材料,具有高阻燃(A类)、低烟、无卤和耐火特性,在继承了BTTZ系列矿物绝缘电缆高度防火特性的同时特殊的结构设计使得电缆耐电压等级、绝缘电阻和弯曲性能均有大幅提高,运行非常节能,可以连续多芯大截面大长度生产,安装也回复到传统电缆安装工艺,施工与维护简便,综合成本大大降低。其优势有:

  

This product only contains small amount of organic material and has high flame retardant, low smoke, halogen free and fire resistant characteristics. In addition to the inheritance of high fireproof characteristic of BTTZ series mineral insulated cables, its special structural design greatly improves voltage resistance grade, insulation resistance and bending property and energy can be saved during operation. Continuous multi-core cables with large section and long length can be produced and the installation also returns to the installation technology of traditional cables. The construction and maintenance is simple and convenient and comprehensive cost is greatly lowered. Its advantages include:

  

1、既有金属护套,屏蔽性能好,抗电磁干扰强,电缆的弯曲性能也好。

3、多芯最大导体截面可生产到185mm2,克服BTTZ 25mm2以上只能生产单芯的不足。

  

3. Maximum multi-core conductor section could reach 185mm2, which overcomes the shortage that only single core can be produced for BTTZ above 25mm2.

  

4、电缆可再生使用,如遇线路改建调整时,电缆可以拆下重复使用。

  

4. Cables could be reproduced and used. In case line is reconstructed and adjusted, cables could be removed to be repeatedly used.
