Appointment
Explosion-proof lamps for luminescent induction lamps like QL, and also gas-discharge lamps are intended for the general lighting of fields, sea platforms, docks and plants in which emergence of explosive gases or dust is possible.
Features
- Application of a luminescent induction lamp like QL allows to cut down energy consumption and expenses on service. Service life of a lamp reaches 80 000 hours.
- Universal fastening on a bracket allows to install the lamp practically on any surface and at any angle.
- The extra-strong plafond with high transparency bears blow of 4 J at a temperature of -40 °C and allows hit of a cold stream of water on the working lamp without loss of strength characteristics.
- Corrosion-resistant materials with a special covering provide long service life.
- Possibility of a complete set of the lamp dome-shaped reflector.
- Two dimensions of the case depending on the power of the used lamps.

Design
- The lamp consists of the aluminum case with a powder covering.
- Protective glass – heat-resistant, extra-strong, with high light-transmitting ability, fastens in an aluminum ring and is twisted in the lamp. The protective lattice is in addition applied to protection of glass.
- In the case the cartridge and terminal clips for power connection are established.
- Leading of a cable is carried out through an opening in a box of introduction office
- The universal system of fastening on a bracket which allows to install the lamp on a ceiling, on a wall, including at an angle, and also at top of columns is provided in the lamp. The possibility of transit laying of a cable is provided in the lamp.
- In and outside of the lamp grounding bolts are established.
Completeness of delivery
By default the lamp is completed with zapglushka with M25x1,5 carving.
Are in addition ordered:
Cable inputs:
- VK-H-VEL1BM-M25kh1,5-Ekhe for an armor cable;
- VK-H-VEL3-M25kh1,5-Ekhe for not an armor cable;
- VK-H-VEL1BMT-M25kh1,5-Ekhe-M25kh1,5 for an armor cable in a pipe or for accession
this cable in a metalsleeve by means of the MMRN-20 coupling;
- VK-H-VEL3T-M25kh1,5-Exd-M25kh1,5 for not an armor cable in a pipe or for accession
this cable in a metalsleeve by means of the MMRN-20 coupling.
At the order of the lamp it is necessary to consider that in the case of the lamp it is cut
M25x1,5 carving.
