2.4 优越性能/ Perfect Performance
高稳定性：该电缆留了刚性矿物绝缘电缆的耐火特性，采用了特有的阻水层，是的电缆具有不宜吸潮等特点，因此绝缘性更稳定。
High stability: the cable stayed the fire resistance of rigid mineral insulated cables, using a unique water resistance layer, is the cable has not the characteristics of moisture absorption, and so the insulation is more stable.
高耐火性能：该电缆采用了陶瓷化材料作为电缆的主防火层，该材料随着火焰燃烧迅速烧结为陶瓷壳，并且温度越高，燃烧时间越长，烧结的陶瓷壳越结实。烧结后的壳体绝缘电阻可以达到1018次方，远远高于其他材料。
High fire resistance: the cable the ceramic material as the master cable fireproof layer, the material with the flame combustion rapid sintering of ceramic shell, and the higher the temperature, the longer burning time, sintering of ceramic shell stronger. The insulation resistance of the shell can reach 1018 times after sintering, which is much higher than other materials.
高耐压等级：该电缆出厂例行试验要承受3500V，5min的耐压试验，所有产品耐压性能优越。
High voltage level: the cable factory routine test to withstand the 3500V, 5min test, all products are superior to the pressure.
生产范围：该电缆采用了陶瓷化工艺，导体采用了绞合导体工艺，产品覆盖了630mm?以下所有的型号和规格，相对于金属护套电缆，本产品的覆盖范围更加广。
Production range: the cable adopts ceramic process, and a conductor adopts the stranded conductor technology, products, covering 630mm facility, all of the following types and sizes, relative to the cable metal sheath, the product coverage of the more widely.
生产长度：该电缆的绝缘层，陶瓷化防火层都是采用了连续挤出的生产工艺，可以根据客户的要求，定长度生产。
Production length: the insulation layer of the cable, the ceramic fire layer is the use of continuous extrusion production process, according to customer requirements, set the length of production.
