Technology | What are the components of strong and weak current cable wiring and smart power distribution cabinets commonly used in LED installation projects?

Strong and weak current cable routing

There are two main ways of wiring strong and weak cables in the LED display project: buried laying and open wire laying.

Concealed laying is to bury the cable to a certain depth underground, and cover the surface with soil and concrete. Usually, this method is to bury PVC pipes or galvanized steel pipes in the ground, place the cables in them, set up wire wells and overhaul boxes at certain intervals for threading and overhaul purposes, and are often used for outdoor cable laying.

Open wire laying is to lay the cables in the trunks, pipes, bridges, and wire wells, which are exposed to the environment, and are often used for cable laying in buildings.

Commonly used supports for cable wiring include PVC line pipes, galvanized steel pipes, metal trunking, and metal bridges, which are all standardized products. At the same time, the pipe diameter and cable ratio are determined by the wiring specifications.

Composition of intelligent power distribution cabinet

The display power distribution cabinet mainly consists of the following parts: power distribution component, indicating conversion component, control signal receiving conversion component, time-sharing power-on control component, and execution component.

Power distribution components include general power distribution devices such as cabinets, bus bars, circuit breakers, etc., which are the basic components of power distribution cabinets.

Indication conversion components include indicator lights, voltmeters, automatic/manual converters, etc., which monitor the working status of the power distribution cabinet and switch the remote and near-end control.

The control signal receives the conversion member. The time-sharing power-on control components include solid state relays and multi-function controllers, which are the core devices for step-by-step power-on of the display screen. The executive component includes an AC contactor, which is a terminal device for wiring the display screen.
