Product Introduction

The JWBT835 Explosion-Proof Telephone is a heavy-duty, VoIP/Analogue industrial phone engineered for hazardous and harsh environments, including petrochemical plants, oil refineries, and construction sites. Built with a high-strength SUS304 stainless steel enclosure, the JWBT835 delivers maximum corrosion resistance, high impact protection, and vandal-proof durability for 24/7 mission-critical communications.

Features

1. Professional Explosion-Proof & Waterproof Performance: Strictly manufactured according to explosion-proof standards, with Ex d IIC T6 Gb explosion-proof grade, suitable for Zone 1/Zone 2 explosive gas hazardous areas. IP66 high-level protection, fully resistant to industrial dust, rainwater splashing and high humidity, adapting to all-weather outdoor and indoor industrial scenarios.

2. Corrosion-Resistant Stainless Steel Housing: Optional 304/316 stainless steel enclosure. 304 stainless steel for conventional chemical and mining plants; 316 stainless steel for coastal, salt-fog and offshore harsh environments, effectively anti-rust, anti-oxidation and anti-chemical corrosion.

3. Backlit Industrial Keypad & Custom Shortcut Dial: Wear-resistant metal integrated keypad with blue backlight, clear key recognition in dark factory and tunnel environments. Three programmable shortcut keys D1/D2/D3, support one-key quick call to workshop, control room and dispatch center, improving emergency response efficiency.

4. Heavy-Duty Industrial Durability Design: Anti-impact rubber handset, oil-proof and wear-resistant, resistant to frequent knocking and collision on industrial sites. Tensile spiral anti-pull cord, effectively avoiding wire breakage and loose contact. Multiple standard explosion-proof cable glands, convenient for on-site wiring and multi-system networking.

5. Easy Installation & Wide Adaptability: Wall-mounted integrated design, no need for additional cabinet equipment, saving installation space and engineering cost. Support custom logo laser engraving and shortcut key function customization, meeting personalized OEM project demands.
