BHC-D-G3/4 cast steel explosion-proof wiring box

1BHC-D-G3/4 cast steel explosion-proof wiring boxProduct Introduction

The product model is BHC-D-G3/4, where:

BHC "represents the explosion-proof wiring box series;

D "represents the left turn structure (90 ° left turn);

G3/4 "refers to a threaded interface size of 3/4 inch (i.e. 6 pipes), which complies with industry standard pipe threads (DN20);

The material is cast steel, with a galvanized surface, which has stronger mechanical strength and corrosion resistance.

Suitable for explosive gas environments in Zone 1 and Zone 2, with explosion-proof type of Exe II Gb, complying with national standards GB 3836.1, GB 3836.3 and IEC60079, with a protection level of IP55, and capable of stable operation in environments ranging from -20 ℃ to+40 ℃.

IIBHC-D-G3/4 cast steel explosion-proof wiring boxMain Features

High strength structure: Made of high-quality cast steel material, formed by one-time die-casting, with no bubbles or sand holes inside, and strong impact resistance (up to 7J);

Anti corrosion treatment: surface galvanizing or high-voltage electrostatic spraying, effectively resisting moisture and chemical corrosion, extending service life;

Reliable sealing: A rubber sealing ring is used between the box body and the cover, which is waterproof and dustproof, prevents sparks from leaking out, and ensures explosion-proof performance;

Flexible installation: supports multiple structural forms (such as left bend, right bend, tee, straight through, etc.), and can be freely combined according to on-site wiring requirements;

Standard interface: G3/4 'threaded interface, compatible with commonly used cable conduits, easy to install, and highly versatile.

3、 Product advantages
