Product Description
The Junction Box serves as an essential enclosure designed to safeguard electrical connections,wiring,and terminals from harmful external factors such as dust,moisture,and mechanical damage.Typically crafted from sheet metal, these boxes can be expertly fabricated using advanced techniques like laser cutting,stamping,and bending.
Sheet Metal Bending Process
A precise force is applied to a metal sheet, skillfully deforming it into the desired shape.
This process is usually executed using a press brake machine,which efficiently uses a punch and die to form accurate and precise bends.
Bending can be adeptly performed on materials such as stainless steel,aluminum,galvanized steel,and other durable alloys.
Material Selection
Mild Steel (MS):Known for its strength and cost-effectiveness,requires surface treatment for optimal rust protection.
Stainless Steel (SS304/SS316):Renowned for its corrosion resistance,perfectly suited for outdoor and industrial environments.
Aluminum:Esteemed for being lightweight and corrosion-resistant,commonly used in electrical and aerospace sectors.
Galvanized Steel:Already pre-coated for enhanced rust resistance,ideal for environments with high moisture levels.
Standard Sizes
Standard size range is from 100x100x50 mm to 400x400x200 mm,but can be tailored to custom dimensions.
Includes convenient mounting flanges or brackets for simple installation.
Features & Components
Comes with pre-cut knockouts for easy cable entry (round,square,or conduit-friendly designs).
Equipped with a lid featuring hinges or screw fasteners for effortless maintenance.
Features gasket sealing (IP65/IP66 rated) for superior waterproof and dustproof protection.
Includes earth/grounding terminals to effectively prevent electrical hazards.
