Elenvator Cable 
The products are suitable for the elevator's signal and control circuit corollary equipment with the alternating voltage 300/500V. The permited long working temperature should be below 65℃.
The cable should hang down freely,and pull open fully before it is installed. The stiffening core should be fixed, while bearing the pulling force. Insulating wire cores use colour or figure marks.The central core must be stiffening core made of hemp and jute or other similar materials.
The insulating wires core enable to endure the soaking voltage test of 2000V 50Hz. The ready cable' s insulating wires core enable to endure the non-soaking voltage test of 2000V 50Hz. The conductor core must not be broken after the ready cable ex-perience the winding test of static state.YTF type cable can ex-perience non-exeending burning test.
