Shenhai Explosion-Proof
As technology advances, LED lighting has become increasingly prevalent, with a growing demand for LED explosion-proof lights in industrial lighting. LED explosion-proof lights offer numerous advantages such as energy efficiency and environmental friendliness. However, if you visit related electromechanical markets, you’ll find that most LED explosion-proof lights are low-priced and of inferior quality. To the untrained eye, these products may seem indistinguishable from standard LED explosion-proof lights. Understanding certain professional knowledge is essential. Here, I will introduce the acceptance criteria for LED explosion-proof lights, enabling you to truly understand and easily identify their quality.
Acceptance Criteria:
1. Identification:
LED explosion-proof lights should have a nameplate with the EX mark, type of elektrické zariadenia odolné proti výbuchu, protection level, and temperature group. The label should also indicate the certifikácia nevýbušnosti number issued by the inspection unit.
2. Compliance:
The protection level, temperature group, environmental conditions, and special markings of the Svetlo LED odolné proti výbuchu must comply with regulations.
3. Integrity of the Casing:
The casing of the LED svetlo odolné proti výbuchu should be free from cracks or damage, the paint intact, and all parts securely fixed, including bolts and anti-loosening devices.
4. Lighting System Stability:
The lighting system of the explosion-proof light should be stable, with correct connections, and inlet and outlet installation positions should meet requirements.
5. Electrical Ingress Sealing:
Redundant electrical entries of the explosion-proof light should be sealed as required.
6. Circuit and Sealing Installation:
The installation of the LED explosion-proof light’s circuit or sealing device should be carried out according to regulations.
7. Wiring Verification:
The wiring of the LED explosion-proof light should be correct, and the routing and elevation should meet design requirements, with the line marked with a sky-blue symbol.
8. Grounding and Anti-Static Requirements:
Uzemnenie or neutralization, and anti-static grounding of the LED explosion-proof light should meet design requirements and be firmly reliable.
