  2、 現有重點、高精尖產品介紹

  2. Introduction of existing major and high-end products

  超柔礦物絕緣防火電纜采用耐火、無污染、高彈性、耐高溫耐火絕緣體絕緣材料，該材料在火災情況下，轉化為無機SiO2陶瓷殼體，起到很好的阻燃、防火、隔水及抗震的作用;電纜采用絞合銅導體，不銹鋼連鎖護套或非金屬高阻燃護套結構，增加了電纜的柔軟性，使電纜的彎曲半徑更小。這些材料一般都具有1400℃以上的較高熔點，因此即使在1050℃高溫條件下防火電纜也能正常發揮輸電功能，且能通過BS 6387的C\W\Z試驗，是一種真正意義上的防火電纜。

  The super flexible mineral insulated fireproof cable adopts with fire-resistant, pollution-free, high-temperature and fire-resistant insulated materials which could be transformed into inorganic SiO2 ceramic shell in case of fire, to play a good role in flame retardancy, fire prevention, water separation and earthquake resistance. Stranded copper conductor, stainless steel interlocking sheath or nonmetal high flame-retardant sheath structure are used in the cable, which improves the flexibility of the cable and reduces the bending radius of the cable. These materials generally have a high melting point more than 1400℃. Hence, the fireproof cable can operate the power transmission normally even under the high temperature of 1050℃, and it could pass the C\W\Z test of BS 6387, which is a real fireproof cable.

  5、 基本原理

  5. Basic principle

  絕緣采用耐火絕緣體材料。在火焰燒蝕下，絕緣材料逐漸分解，生成二氧化硅為主體結構的陶瓷狀無機絕緣體，附著在導體表面，這種絕緣體具有隔熱、絕緣、耐火功能和較大的機械強度，能夠確保電纜在火焰并附加機械沖擊和噴淋狀況下保持一段時間正常工作。

  The fire-retardant insulation materials are adopted for insulation. The insulating materials decompose gradually under combustion to form a ceramic inorganic insulator with the main structure of silicon dioxide attached to the surface of the conductor. This kind of insulator has functions of heat-retardancy, insulation, fire-resistance and high mechanical strength, which ensures that the cable can operate normally for a while under the condition of flame and additional mechanical shock and spray.

  6、 材料特性

  6. Characteristics of materials

  絕緣層采用耐火絕緣體材料，在常溫下具有普通橡膠、硅橡膠及熱塑性彈性體一樣的優異性能，屬于無鹵、無毒、無味環保型產品;同時在火災、高溫的情況下，迅速生成陶瓷狀堅硬、完整的硬殼，該殼體能夠在遇水噴淋、震動等情況下也不會破損，這是耐火絕緣體區別于目前所有高分子材料的“革命性”特點。

  The insulating layer adopts fire-resistant insulator material with excellent performance as ordinary rubber, silicon rubber and thermoplastic elastomer at room temperature. It belongs to halogen-free, non-toxic, tasteless and environmental protection products. Meanwhile, the ceramic hard and complete shell can be formed rapidly in case of fire and high temperature. The shell cannot be damaged in case of water spray and vibration. This is the “revolutionary” characteristic of the fire-resistance insulator that is different from that of all polymer materials at present.
