6～35 kV XLPE绝缘耐火电缆的研制

Development of XLPE Insulation Fire-Resistant cables for Rated Voltage 6-35 kV

介绍了额定电压6～35kVXLPE绝缘耐火电缆的结构，通过设计隔热耐火层、内衬层、铠装、外护套组成复合耐火层，实现电缆的耐火性能。

This paper introduced the structure of the XLPE insulated fire-resistant cable with the rated voltage from6 kV to 35 kV. The fire-resistant performance can be realized by the usage of composite refractory layer which is made up of heat insulation refractory,inner covering,armor and outer sheath.
