Xl-21 低压配电柜
The XL-21 low-voltage power distribution cabinet (box) is appropriate for industries and mines such as metallurgy, mining, petroleum, chemical industry, textile, ports, stations, etc., as a three-phase three-wire AC 50Hz, rated voltage 400V or 660V, rated current 630A It is used in low-voltage power distribution systems with four or five wires to distribute electricity and provide lights. It may also be used to regulate squirrel cage and wound-type motors in low-voltage control systems.
说明
- XL-21 power distribution box is divided into two types. The box height 1700mm and 1800mm is the ordinary type (P type).
- The box is installed independently and the top can be opened and accessed according to the requirements.
- Wire holes: cabinets with a height of 1900mm and above are top busbar type (M type), and the top of the box is equipped with a removable cover to facilitate busbar installation and removal.
- Using precision cast adjustable door hinges, the door can open more than 135°. The mounting bracket in the box can be adjusted as a whole after the components are installed. Can be installed according to different usage environments
- It has strong versatility and can be used in combination with multiple units. The power cabinets are made separately. Wire holes are opened between the cabinets in a well-communicated manner, and the channel steel base is designed to correspond to all the
- The width of the cabinet is individually configured, that is, one cabinet is equipped with an independent base, and the mounting holes for the ground are punched. All floor-standing cabinets need to be equipped with lifting rings (including indoor and outdoor), and the lower part of the power cabinet
In addition to the regular stock sizes of the power distribution cabinet, the width (400~1000mm), height (1600~2200mm), and depth (400~800mm) can be adjusted arbitrarily according to actual needs.
