Electrical safety solutions specialist Douglas Electrical Components (DEC) has announced the release of a new whitepaper focusing on the crucial role of wire bushings in designing safe electrical systems for hazardous locations.
Wire bushings, often overlooked, are vital components ensuring safety and compliance in hazardous areas such as liquefied natural gas (LNG) handling and factories with combustible dust.
These seemingly minor components play an outsized role in preventing leaks around wires passing through pressure walls, thus ensuring safety and compliance with agency requirements.
In the past, finding customisable wire bushings meeting compliance standards for hazardous locations posed challenges. However, DEC introduces an innovative approach utilising epoxies to create hermetic seals around wires, simplifying compliance with regulations without compromising design freedom.
Epoxy-based wire bushings have a proven track record, exceeding UL, ATEX, IEC, and FM leakage requirements with leak rates less than 1×10-8 cc-He/sec. These seals prevent potentially dangerous leaks of flammable gases or combustible materials, even at cryogenic temperatures.
To streamline the certification process, Douglas Electrical Components obtained a key UL listing for their explosion-proof wire bushings. With a UL 1203 listing, customers can avoid lengthy and costly individual certification processes for wire bushings in explosion-proof applications.
The whitepaper also highlights two lesser-known design features of Douglas Electrical Components’ UL 1203 bushings:
- Full chemical compatibility: Epoxy offers high-end fatigue properties and resistance to environmental stress cracking, ensuring long-lasting sealing in the field.
- Combined explosion and process seal: The UL 1203 bushings provide a true hermetic process seal, simplifying installations in hazardous locations.
DEC’s whitepaper not only addresses the challenges of hazardous location standards but also introduces innovative solutions to meet evolving industry needs.
