Low-voltage power distribution cabinet alias outdoor power cabinet
- Oct 09, 2018 -

Low-voltage power distribution cabinets are aliased for outdoor power cabinets. Power distribution box outdoor distribution box site box custom power cabinet XL-21

The conventional size is 1800/800/400. The material is cold rolled steel. The color of the beige color is generally between 1.0 and 1.2.

The low-voltage power distribution cabinet is a new low-voltage power distribution cabinet designed according to the requirements of the superior department of the Ministry of Energy, the majority of power users and the design department, in accordance with the principles of safety, economy, rationality and reliability. The incoming mode has the upper, lower and top left, middle, right and back of the cabinet to meet the needs of different types of engineering. At the same time, there is a fixed position in the cabinet to install electromechanical protection and automatic devices for power plants and special users. The product has high breaking capacity, good dynamic thermal stability, flexible electrical scheme, convenient group operation, strong series and practicability, novel structure, high characteristics, and can be used as a new generation of low-voltage switchgear.

Features

It is safe, economical, reasonable and reliable. Widely used in power plants, substations, industrial and mining enterprises, mines, stations, hospitals, etc.; with high breaking capacity, good thermal stability, flexible electrical scheme, convenient combination, series and practicality, novel structure; rated current can be Increased to 3150A, suitable for distribution transformers below 2000kVA; the cabinet mainly uses domestic electrical components that can be mass-produced and stable in process. It can also be installed with imported components; HD13BX and HS13BX rotary operated knife switches are special components designed to meet the unique structure of the GGD cabinet. It changes the operation mode of the mechanism and retains the advantages of the old product. It is a practical type. Electrical components; busbar clamps are thermoformed from high-strength, high-flame-retardant PPO alloy materials, with high insulation strength and good self-extinguishing performance; the frame is assembled by partial welding of 8MF cold-formed steel; the cabinet topcoat is made of electrostatic epoxy powder. Spraying, strong adhesion, good texture, orange pattern international gray; cabinet - IP30, users can also choose between IP30-IP40 according to the requirements of the use environment.


Conditions of Use


a. The ambient air temperature is not higher than + 40 ° C, not lower than -5 ° C. The average temperature within 24 hours shall not be higher than + 35 ° C;


b. Indoor installation and use, the altitude of the place of use shall not exceed 2000M;


c. The relative humidity of the surrounding air does not exceed 50% at a maximum temperature of + 40 ° C, and allows a relatively large relative humidity at a lower temperature (for example, 90% at + 20 ° C) should be considered due to temperature changes may be accidental Produce the effects of condensation;


d. The inclination of the equipment when installed is not more than 5%;


e. The equipment should be installed in a place where there is no severe vibration, and where the electrical components are not corroded; if the user has special requirements, it can be negotiated with the manufacturer.
