Product Details

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.

Communication cables are used for communication engineering wiring, connections between indoor telephone communication cable system wiring, trunk lines between voice communication systems, program-controlled switches, telephones, faxes, and digital telephone connections. The telephone lines can be made in insulated pairs - the individual insulations are twisted in pairs at different pitches and the specified chromatographic combination is used to identify the pairs. This is advantageous in reducing crosstalk between the clues and reducing power consumption.
