What is Cast Aluminum Explosion Proof Junction Box?
Cast Aluminum Explosion Proof Junction Box is a special type of electrical distribution equipment specifically designed for use in flammable and explosive environments. Its core function is to prevent explosions caused by electrical factors such as electric arcs and sparks. It plays a crucial role in safe production.
The casing is made of high-quality die-cast aluminum alloys such as ADC12 and YL02/YL04, featuring a robust structure that effectively prevents dust, water, corrosion, and explosions, making it suitable for harsh environments such as outdoor, humid, and chemically corrosive conditions.
What is the function of Cast Aluminum Explosion Proof Junction Box?
Internal components: Divide the main circuit into multiple paths, include switches to control current, and incorporate protective devices.
The distribution box itself is waterproof and dustproof for internal wiring and prevents accidental contact by external personnel.
Cast Aluminum Explosion Proof Junction Box: While ordinary distribution boxes are sufficient in simple environments, complex industrial environments, especially flammable and explosive chemical environments, necessitate additional explosion-proof features. Cast aluminum distribution boxes are thicker and, with their explosion-proof surfaces, ensure safer use of electricity during production.
What materials are used in Cast Aluminum Explosion Proof Junction Box?
01
ADC12 (Die Casting)
ADC12 is the most commonly used material for die-cast explosion-proof distribution boxes. It can be used to cast complex box structures, and the ribs and screw posts can be cast very well. It has a beautiful surface and looks great after powder coating.
02
YL02 (Die Casting)
This material is characterized by not containing copper and zinc, having better corrosion resistance than ADC12, and good airtightness. However, its strength is slightly weaker. This material is chosen when high corrosion resistance is required but strength requirements are not high.
03
YL104 (Die Casting)
YL04 contains magnesium, and its strength and explosion-proof performance are higher than ADC12. However, die casting is also more difficult than ADC12, resulting in a slightly higher cost. It is mainly used for IIC high-level explosion-proof boxes.
04
ZL02 (Gravity Die Casting)
This material is relatively soft but has high corrosion resistance. Generally used only for large-size, low-pressure, non-high-risk explosion-proof boxes.
05
ZL04 (Gravity Die Casting)
ZL04 has the advantages of being comparable to YL104, with high toughness and high strength. It is the most commonly used material for recast aluminum alloy explosion-proof boxes.
What quality inspections should be paid attention to for Cast Aluminum Explosion Proof Junction Box?
Quality inspection is the customer's primary concern and our top priority. Shata Machinery rigorously controls every step to ensure that only qualified products are delivered to our customers.
- Visual Inspection
+
-
Appearance is generally determined by visual inspection;
photos and videos will be sent upon customer request;
Surface should be smooth and flat, free of pits, holes, cold shuts, etc.
No cracks, deformations, or defects.
The box body and cover should fit smoothly.
No welding or repairs.
- Internal Density Inspection
+
-
Internal density is crucial for explosion-proof safety and is a key inspection item.
We conduct meticulous testing on the first sample, recording all machine parameters. Once the product passes inspection, production proceeds according to the parameters. During mass production, a proportional sampling inspection is conducted, and an inspection report is sent to the customer. Optional X-ray detection and pressure testing.
- Explosion-proof surface inspection
+
-
The surface is bright and smooth, free of scratches, etc.
Roughness meets the requirements of the drawings. The enclosure and lid fit tightly.
- Dimensional inspection
+
-
Dimensions as indicated on the drawings meet the tolerances.
- Surface treatment
+
-
Uniform color, no bulging or peeling on the surface, clean appearance.
