Product Introduction
Technical Introduction to the Enclosure of XL-21-Type Power Distribution Cabinet
I. Overview
The enclosure of the XL-21-Type Power Distribution Cabinet is a "closed dust-proof" low-voltage power distribution device enclosure. Specifically designed for industrial environments, it meets the needs of "power distribution" and "motor control" in various scenarios.
II. Enclosure Material and Manufacturing Process
1. Main Body Material
High-Quality Cold-Rolled Steel Plate: Mainly uses high-quality cold-rolled steel plates (SPCC) with a thickness of 1.5-2.0mm
Surface Treatment:
Degreasing and phosphating treatment
Electrostatic spraying (standard color: RAL7035 light gray)
Average coating thickness ≥ 60μm
Strong adhesion and good corrosion resistance
2. Optional Materials
Stainless Steel: Suitable for corrosive environments (SUS304)
Galvanized Steel Plate: Enhances rust resistance (SGCC)
Aluminum Alloy: Used in special explosion-proof occasions
3. Manufacturing Process
CNC Machining: Processed by CNC punching machines and bending machines
Welding Process: CO₂ shielded welding, with uniform and smooth weld seams
Assembly Method: Partial bolt connection for easy on-site assembly
4. Protection Level and Sealing Performance
Standard Protection Level:
IP40: Prevents the entry of solid foreign objects with a diameter ≥ 1.0mm
Upgradeable Options:
IP54: Dust-proof and splash-proof (additional sealing measures required)
IP65: Dust-tight and spray-proof (special customization)
Sealing Design:
Door Frame Sealing: High-quality rubber sealing strips are used
Wire Inlet/Outlet: Reserved knock-out holes or additional cable sealing joints
Ventilation Design: Optional dust-proof ventilation hoods or air conditioning interfaces
