The high-frequency cable insulation structure, in addition to the old paper yarn tape insulation structure, has been producing foam polyethylene, polyethylene insulation rope polyethylene pipe insulation, fish bubble insulation, polystyrene insulation rope, etc.
The largest foam polyethylene insulation of the cable. In the integrated and small coaxial cable integrated coaxial cable, high frequency four quads (four quads) and low frequency is also using polyethylene foam insulation structure. This structure has the advantage of processes and equipment being simple.
