Point.Cable service life is directly related to the aging life-span of cable insulation material, and the thermal lifetime of therefore insulant is direct
Affect the service life of cable., if long-term work is allowed in itself with product taking irradiation crosslinking halogen-free low-smoke fireproof cable as a example
105 degree of derivations of rated temperature, its thermal lifetime was more than 60 years, if being derived with operating temperature for when 90 degree, its thermal lifetime
More than 100 years, however, irradiation crosslinking halogen-free low-smoke fireproof cable processing mode when producing is complicated, operation was more, not easily-controllable
System, must repeatedly stand " irradiation ", the height producing uniformly through high-energy electron accelerator back and forth after the insulating exruded cooling of cable
Energy electronic beam current carries out the process of cross-linking radiation to cable.As can be seen here, as irradiation crosslinking halogen-free low-smoke fireproof cable, high energy
Electron accelerator and expensive irradiation crosslinking halogen-free low-smoke and flame retardant material are necessary requirements.And at present according to incompletely statistics, domestic electricity
Cable industry more than 7000, high-energy electron accelerator only more than 60 platform, be wherein used for only more than 50 platforms of cable processing, completely offset from
Cable industry produces the demand of irradiation crosslinking halogen-free low-smoke fireproof cable necessary requirement, thus causing to produce irradiation crosslinking halogen-free
Irradiation and freight be increased on the cost of low-smoke fireproof cable, and Some Enterprises irradiation apparatus in cable irradiation processing industry
As electron accelerator design does not reach requirement, not, the product degree of cross linking after irradiation not, fails to reach modification detection meanss
Require, product hands over inspection qualification rate low, there are larger quality problems.
