SYWV(Y)-75The high hair of physics of polyethylene steeps the cable

The description of products :

Cable high quality cable who air insulateds polyethylene lotus root form medium radio frequency Model SYWV, Used in the communication, have following characteristics

1.It is low to transmit and loss , the width that work frequently

2.Weight is light, easy to lay and install

3.It is reliable that electric performance is steady

SYWV(Y)The coaxial cable is used in CATV, the closed-circuit TV waits for the transmission systems of VHF and UHF signal, is regarded as the main line in the system, Branch line and feedback cable of other electronic devices

The electric performance of the cable:

SYWV(Y)-75The high hair of physics of polyethylene steeps the cable

The description of products:

Type polyethylene physics high hairses steep SYWV( Y) cable that each it has to be very low cable who medium losses, It to inject into and make medium send and steep, choose proper technology make and it forms to be very light close air vent each other through gas, This kind of medium is difficult to wear out, it is difficult to make moist. The body is a red copper line in the cable, the other conductor is that the aluminum pipe or the aluminium is moulded and brings and add the tin-plated copper wire to weave, Medium and interior conductor each other firm combination, it when change or play pressing in temperature, Will not be moved relativly between the medium and conductor.

SYWV( Ys)ses 75 type the decays of cable than with sizes other radio frequencies cable little,last CATV and closed-circuit TV system, transmit high frequency and ultra-high frequency signal of its, Its parameter has already reached the international radio frequency cable standard.
