Flameproof explosion proof led lights and flameproof electrical equipment cable introduction device selection points

What is flameproof explosion proof led lights ?

Flameproof explosion proof led lights based on the basic principles of the European standard EN13463-1:2002 “non-electrical equipment for use in explosive environments, Part 1: Basic Methods and Requirements” of the flameproof basic concepts and fire safety categories, flameproof type is to take effective measures to allow the internal structure of the explosion and block the spark transmission explosion of a type of flameproof type is very commonly used in a type of flameproof type.

　　Because this flameproof type of lighting fixture housing generally use metal composite materials manufacturing, heat exclusion, housing strength and durability, favored by users. And, many flameproof electrical components, such as sockets, interlocking power switches, etc., also choose flameproof construction. Electrical equipment with flameproof housing is called flameproof electrical equipment.

　　If the explosive gas mixture into the flameproof enclosure and was ignited, flameproof enclosure can withstand the internal structure of the explosive gas mixture of deflagration pressure, and block the internal explosion to the enclosure surrounding the combustible mixture of material dispersion.

　　This is a gap flameproof principle, that is, with the help of metal material gaps can prevent the spread of explosive sparks and refrigeration of the temperature of the products of the explosion to achieve the spark extinguished and attenuated, inhibit the expansion of the explosion of the principle of a structure.

Flameproof explosion proof led lights and flameproof electrical equipment, what are the requirements of the cable introduction device?

flameproof explosion proof led lights and flameproof electrical equipment should be selected metal cable introduction device, and match the diameter of the cable, should not use other materials to make the cable to match the cable introduction device.

One of the following forms can be selected:

1. a cable introduction device sealed by a compound packing and obtaining an flameproof certificate of conformity as equipment;

2. a cable and introduction device that meets all of the following requirements:

(1) Cable introduction devices which have obtained an flameproof certificate of conformity as flameproof equipment;

(2) Use of thermoplastic-sheathed, thermoset-sheathed, or synthetic rubber-sheathed cables. The cables shall be round, dense, and any bedding and sheathing shall be extruded and the filler, if any, shall be nonhygroscopic;

(3) The minimum length of connected cables shall be 3 m.

3. indirect cable introduction by means of a combination of an flameproof enclosure with a sleeve and a safety-increasing junction box;

4. mineral insulated metal sheathed cables with plastic sheaths or without plastic sheaths, with the corresponding flameproof cable introduction device;

5. for the equipment documentation specified in the flameproof sealing device (eg sealing cavity), the cable introduction device with the cable used to adapt. The sealing device shall have a compound packing seal or other corresponding seal allowing filler around the individual cores. The sealing device shall be installed close to the cable introduction device.

NOTE 1: The minimum cable length is intended to minimize the possibility of flame propagation through the cable;

NOTE 2: If the cable introduction device and the actual cable are licensed as part of the equipment (enclosure), compliance with the requirements of this article is not required.

In order to meet the requirements of the protection class, sealing measures (e.g. the addition of a sealing washer or thread sealant) should also be taken between the cable introduction device and the enclosure.
