Individual insulated wire cores are all the outer extruded insulation layers of conductor, and such effect that extrudes is bad, is easily ftractureed when extruding, and waste material
Material.
In order to save more life, property and information from the scene of a fire of mercilessness, it during being applied to of fireproof cable is attached most importance to
Weight, and fireproof cable in the market can be divided into two kinds of rigidity and flexibility by architectural characteristic.Due to rigid mineral insulation electricity
Cable rigidity mineral insulated cable（Mineral Insulated Cable）Abbreviation MI cables are in terms of reliability, production and laying
The defects of, gradually quit listing in European and American developed countries, the main flow cable that flexible mineral insulation fireproof cable turns into fire protection field produces
Product.General cable metal set uses copper sheathing, and technique is complex, and efficiency is low, and cost is higher, and separation layer is passed through frequently with heated temperature
Relatively low material is spent, isolation can not be formed so that isolation material is heated by broken meeting, phenomena such as frequently resulting in cable short circuit.
With the substantial increase of China's super-pressure and high voltage power cable laying amount, the safe for operation and quality of power cable
Monitoring is more and more important, it is necessary to utilize distribution type fiber-optic measuring system（DTS）Enter trip temperature, transmission load monitors in real time, to super
High pressure and high voltage power cable realize that internal or external extraordinary temperature measuring optical cable turns into optical fiber composite high-voltage cable, i.e., so-called " intelligence
Energy cable ".Meanwhile Utilities Electric Co. has included " integration of three networks " Pilot project construction of intelligent grid, national grid is pushed in the whole nation
Power optical fiber is registered one's residence, it is desirable to realize power network end electric power and communicate " integration " power optical fiber to family photoelectric compound cable.
