HYA53
Copper core solid polyolefin insulated aluminum plastic composite sheath single layer longitudinal wrapped steel strip armoured polyethylene sheathed inner communication cable
Transmission of audio, 150Hz and the following analog signals can be buried directly in the field.
HYAT53
Copper core solid polyolefin insulating filled polythene sheathed polyethylene sheathed strip steel strip armoured polyethylene sheathed inner communication cable
The 553 type mechanical protective layer can be added to any structure cable to increase the mechanical strength and improve the erosion resistance of the cable. It is a telephone cable designed for vulnerable areas and easily eroded areas. It can be laid in any way, and it is more suitable for direct burial laying in rock area.
HYA53 and HYA553 type cables are only used in special circumstances, and air pressure maintenance must be carried out in use.
