Explosion-proof light fittings
Descriptions
The enclosures of explosion-proof light fittings are manufactured of die-cast aluminum alloy, with epoxy resin powder sprayed on the surfaces. Therefore, they have good anti-corrosion performance. The transparent shield is made by the toughened glass borosilicate, and the exposed fasteners are made of stainless steel. Explosion-proof light fitting’s terminal box side entry, is suitable for rubber-coated and the armored cable wiring. The internationally certified PHOENIX cage type terminals are selected as the internal terminals, which are convenient for wiring. The unique heat insulation design united with the exterior high density radiator in the explosion-proof light fitting to cause the radiation effect will be better. The LED light source and stabilized voltage supply is supplied inside. It can satisfy the related requirements of illumination in petrochemical, chemical and marine industries.
Explosion-proof light fittings can be sorted as: bracket lamp, platform lamp and wall lamp.
Explosion-proof bracket type lamps can be sorted as: ceiling type, wall sunction type and chain type.
The mounting ways of the explosion-proof platform light fittings C-90°C are fence type and platform flange type.
The mounting ways of the explosion-proof platform light fittings D-25°C are fence type and platform flange type.
- It is energy-saving and environmental protection which the power consumption is only 19% of the same brightness of incandescent lamp.
- It is long life and maintenance – free which the service life is up to 50000 hours and the maintenance-free of long term.
- There is a feature of good electromagnetic compatibility and it does not cause interference to the system power grid.
- It is not influenced by the voltage fluctuations and can be operated in the wide voltage range of AC100 ~ 240V
- There is a good performance of vibration due to the LED is the solid-state light source
- The highest class of flameproof is up to IIC.
- The degree of protection is up to IP66
- It is convenient to be mounted and maintained
- International IECEx Approval, Europe union ATEX Approval.
