May 29, 2018


Definition of Digital cable

1: Cable television made of one or more mutually insulated conductors and an outer insulating protective layer that transmits power or information from one place to another.

2: usually consists of several or several groups of wires (at least) two in each group of twisted rope like cable, insulated between each group of wire, twist and often revolve around a center, the bread has a highly insulating layer.The cable has the characteristics of internal power supply and external insulation.


Classification of Cable and internet

Cables are power cable, control cable, compensation cable, shielded cable, high temperature cable, computer cable, signal cable, coaxial cable, fire-resistant cable, Marine cable, mine cable, aluminum alloy cable and so on.They are made up of single or multiple strands of wire and insulation that are used to connect circuits, electrical appliances, etc.

According to the system of the photovoltaic power station, the cables can be divided into dc cables and ac cables, which are classified as follows according to different USES and use environments:

1. Dc cable

(1) series cables between components and components.

(2) parallel cables between and between the clusters to the dc distribution box (junction box).

(3) cable between dc distribution box and inverter.

The above cables are all dc cables, with more outdoor laying. They need to be moisture-proof, sun-proof, cold-resistant, heat-resistant and ultraviolet resistant.

2. Ac cable

(1) connection cable from inverter to booster transformer.

(2) the connection cable between the booster transformer and the distribution device.

(3) connection cables from power distribution devices to the power grid or users.

This part of cable is ac load cable, which is installed in the indoor environment. It can be selected according to the general requirements of power cable selection.



Network cable applications

The power system

Power system used in wire and cable products mainly include overhead bare wires, bus (bus), power cable, power cable (plastic cable, the paper (basic) they were replaced by plastic power cables, rubber sets of cables, overhead insulated cables), branch cable to partly replace bus (), electromagnetic wire, and power equipment with electrical wire and cable equipment, etc.

Information transmission

The main wire and cable used in information transmission system are Local cable tv, TV cable, electronic cable, rf cable, fiber optic cable, data cable, electromagnetic wire, electric power communication or other composite cables, etc.

The instrument system

This part is used in almost all products except overhead naked wire, but mainly power cable, electromagnetic cable, data cable, instrument cable and so on.
