HYV telephone line
Scope of application:
For indoor telephone lines, doorbell intercom systems, data transmission, etc.
Features:
The cable core is composed of a plurality of mutually insulated wires or conductors, and the outer communication line has a sealed sheath. Some are also equipped with an outer sheath on the outside of the sheath. There are various laying methods such as overhead, direct burial, pipeline and underwater. It has the advantages of large communication capacity, high transmission stability, good confidentiality, and less influence by natural conditions and external interference.

Structure Representation >>
|
Copper conductor --------------------------------------------------------- High purity oxygen free copper has good electrical conductivity, high efficient power transmission and electrical signals, and low loss. |
 |
 |
HDPE --------------------------------------------------------- High density polyethylene non-toxic, tasteless, odorless, and more environmentally friendly. And it has good heat resistance and cold resistance, indicating a higher hardness, tensile strength, stiffness and other mechanical strength, insulation properties and more stable. |
|
PVC / LSZH sheath --------------------------------------------------------- Environmental protection PVC sheathed, acid and alkali resistance, abrasion resistance, oil resistance, oxidation resistance (not easy to aging), more durable. |
