Description

Fire resistance testing tool suitable for fire-retardant power cable Technical Field The utility model belongs to the technical field of cable testing equipment, and particularly relates to a flame retardance testing tool suitable for a flame retardant power cable. Background The flame-retardant power cable has special fireproof performance, can limit flame spreading when a fire disaster occurs, and can fight for personnel evacuation and fire rescue and reduce fire hazard. In the process of production and processing of the flame-retardant power cable, in order to ensure the flame-retardant performance of the flame-retardant power cable, operators use a horizontal and vertical combustion tester to burn the flame-retardant power cable, so that the flame-retardant performance of the flame-retardant power cable is judged by recording data such as the flame spreading distance, the flame speed and the like according to the combustion condition of a flame-retardant power cable sample, but when the horizontal and vertical combustion tester is used, the fire-retardant power cable of equipment internal combustion can produce the flue gas, and after the test, operating personnel can start the inside exhaust fan of equipment, lets these flue gases can directly discharge outside through the blast pipe, and contains particulate matter and harmful substance in the flue gas, and the flue gas will escape in the environment at this moment, leads to operational environment to be polluted, and the flue gas is inhaled by operating personnel after simultaneously, also can influence operating personnel's health.
