Mining floodlights VAT 51-PR-Sh (up to 300 W)

Purpose

Floodlights of this series can be used both for stationary local lighting in coal beds and in other places containing explosive gas according to explosion protection marking.

Features

• Floodlight slope angle shall be adjusted within the range of 360° horizontally, from +60° to -60° vertically.
• High-strength glass with high degree of transparency is additionally protected with grating.
• Parabolic reflector extended along lamp axis ensures narrow-directed light ray.

Design

Body material is aluminum alloy with powder coating, which forms explosionproof enclosure with “d” explosion protection type.

Protective glass is thermal-resistant, extra strong with high light-transmission capability, fixed inside aluminum ring and screwed to lighting fixture. Protective grating is used additionally for glass protection.

Inside the body reflector, bulb holder and terminal clamps for powering on are installed. Grounding bolts are installed inside and outside lighting fixture.
