Cables of PTYV, PTYVH, PTYY, PTYH22, PTYA22, PTYA23, PTYL22, PTYLH22, PTYL23 are mainly used for transferring rating signal when AC rating voltage is not more than 500v or DC 1000v, fixed laying railway signal and some automatic facilitiesĄ¯ transferring controlling line. It can transfer general automatic signal of information, collection and close of the railway. It has the ability of shielding, can be applied to electric railway area and other place with strong interference. The working temperature canĄ¯t exceed 70oc, laying temperature is ¨C5oc~20oc. It can lay under the earth, in the trough and pipe, and can endure more mechanical force. The bending radius is not 15 times less than cable outside diameter.
