Explosionproof traffic light VELAN 61

Purpose

Explosionproof traffic light is used for traffic control at the enterprises of oil and gas processing industry, chemical and pharmaceutical industry – at the enterprises with explosive gases IIA, IIB, IIC and flammable explosive dust.

Features

• LED light source ensures low energy consumption for light traffic and long range of signal identification.
• Modular system of traffic light ensures its simplicity and reliability.

Design

The traffic light consists of modules joined in single design. The module consists of explosionproof enclosure with “d” explosion protection, in which light source and thick-wall glass installed in enclosure cover are located. Above the glass on enclosure light filter is fixed determining color of light traffic module signal.

The traffic light has at least two cable glands. Visor installed on each light traffic module ensures increasing signal viewing distance. Grounding bolts are installed inside and outside.

VELAN61 – Х1 – Х2 – Х3 Х4 V1.5

VELAN61 – explosionproof light traffic

Х1 – pit and mining version (I group of electrical equipment for use in minings and pits). Regarding version for other industrial branches (II group of electrical equipment), index is not specified

Х2 – module light-emitting color:

     R – red

     Y – yellow

     Z – green

     B – blue

     W – white

Application: at number of modules to be more than one letters shall be indicated in sequence. Number of letters determines number of traffic light modules

Х3 – type of light source: SD.L. – LEDs

Х4 – current type (АС/DC) and supply voltage, V (12, 24, 36, 127, 220)

V1.5 is a type of climatic version and arrangement category according to GOST 15150

Example of order forming:

VELAN 61-KZhZ-SD.L.(АС220)-V1.5

That corresponds to:

Explosion proof traffic light with 1ExdIICT6 explosion protection consisting of one red module, one yellow module and one green module. Light source is LEDs, alternating current, voltage 220 V.

Explosion protection marking: 1ExdIICT6 or РВ ExdI

Nominal supply voltage, V: 12, 24, 36, 127, 220

Frequency of supply voltage, Hz: 50

Power of one module, W: 5
