In general, unit selection and configuration of an electric switching equipment will be begin from the following aspects:
● Cabinet choices:
The materials have cold rolled steel or angle iron (for welding cabinet, low cost, high strength general-purpose type); deposited aluminum zinc steel or galvanized steel (used to assemble the cabinet); stainless steel plate (not permeability) ; aluminum ((permeability); the SMC composite unsaturated materials.
Installation types: indoor and outdoor.
● The cabinet's main electrical components brand choice:
High price: ABB, Schneider, United States AB, Mitsubishi, Siemens, Omron, Muller, Weidmuller, Phoenix, Hager, Legrand, etc..
Moderate price: Changshu, the Long March, China through Shanghai Wuchang, Shihlin, refinement, and so on.
Low price: Tengen, Chint, West Germany, the people of appliances, Watertown, Taian, river, etc..
● Cabinet auxiliary components
Copper busbar connections, aluminum row connection and wires connected.
■ Control box / cabinet classification
A single control box / cabinet
Control box / cabinet
Simple control box / cabinet
Intelligent control box / cabinet
Built-in control box
Independent control box / cabinet
■ Structure
Cabinet by steel sheet metal forming, take the 20mm modulus for the standardized design, with versatility of structural components and high mechanical strength;
upper cabinets body is main busbar room, the front is the electrical room, the rear is the cable in/out chamber, each room have steel or insulation board for isolation in order to ensure safe usage;
There have galvanized or two kinds of electrostatic powder coating on the surface protective layer of the cabinet structure parts, so it with reliable quality and beautiful color;
■ Dimensions
Number of electrical components according to user needs and the control box / cabinet is belongs to a custom product.
■ Installation:
Household type, outdoor type and semi-outdoor type
■ Order Attention
The user should be provided (the user can also provide specific requirements, all of the following are required to provide information for the user by the Company engineers designed and then handed over to the production after the final validation of the user):
1.Primary circuit of the program and in-line system diagram;
2.Secondary circuit diagram, if the user does not make demands, will take the factory standard wiring;
3.Switchgear the Pareto substation plan;
4.Detailed specifications for each loop circuit elements;
5.The control box / cabinet surface color;
6.Other special requirements.
