Introduction on the current carrying capacity of YTTW series flexible fireproof wires and cables

Introduction on the current carrying capacity of YTTW series flexible fireproof wires and cables:

The continuous load current carrying capacity(rated current)of wires&cables is an important and complex physical quantity,it is always various in catalogue of domestic and international manufacturers.It is hard to explain the causes for difference,but there is a common ground that these manufactures follow the IEC international standard.Likewise,we completely follow the current carrying capacity of flexible fireproof wires and cables stipulated as the IEC287 standard.The basis is ambient temperature 40℃ and core temperature 90℃.Due to excellent high temperature resistance character of inorganic insulated wires and cables,the improvement of conductor temperature and reduction of the cross section are allowable,but we don’t courage that,because these behaviors will increase the loss of copper,to consider from the comprehensive economic benefit,it is uneconomical.
