FAQ

Q1: What are the core differences between explosion-proof connectors and ordinary industrial connectors?
A1: Explosion-proof connectors are specially designed for explosive hazardous environments, with flameproof or increased safety structures that prevent internal arcs and sparks from igniting flammable gases or dust in the surrounding area. They also feature far higher protection grades, corrosion resistance grades and mechanical strength than ordinary connectors, enabling long-term stable operation in harsh conditions with moisture, vibration and corrosion, and meeting the safety requirements for hazardous areas such as Zone 1, Zone 2, Zone 21 and Zone 22.Q2: How is the system’s power supply and safety guaranteed?

Q2: What are the key precautions for the installation and use of explosion-proof connectors?
A2: Before installation, check whether the product’s explosion-proof mark and specification parameters match the on-site environment; during wiring, operate in strict accordance with the manual to ensure reliable cable sealing and undamaged flameproof joints; fully tighten the threads when connecting to avoid loosening; never plug or unplug under load during use, and regularly inspect the status of the housing, seals and contacts to prevent aging, corrosion or loosening from affecting the explosion-proof performance.

Q3: What are the common protection and corrosion-proof grade standards for explosion-proof connectors?
A3: Commonly used industrial protection grades are mostly IP66 or above, which are completely dustproof and water-jet proof, suitable for outdoor and humid environments. Common corrosion-proof grades are WF2, which can resist the erosion of corrosive media such as salt spray and acid-base, meeting the requirements of highly corrosive working conditions such as marine engineering and chemical workshops; higher grades of corrosion or protection products can be selected for some special scenarios.
