Douglas Electrical Components offers an extensive range of explosion-proof wire and cable seals for simplified engineering in hazardous locations. Our wire and cable seals, commonly referred to as line bushings, offer unique design features that enhance efficiency and reliability of your applications. Available standard with threads in various sizes, these explosion proof cable bushings are pre-wired and sealed for drop-in use, from the factory to the field. The bushing is pre-potted with our moisture-tight, hermetic epoxy to protect either side of the feedthrough from air or liquid penetration. Specify virtually any wire or cable type (with the ability to combine different size conductors) within a single assembly and receive a pre-tested and certified cable bushing ready for install.
With a longstanding expertise in hermetically sealing wires and cables, Douglas can create a high-density cable and wire feedthrough with various jacket materials. Our wire and line bushings use a hermetic epoxy that offers excellent chemical compatibility, thermal properties, and mechanical properties, exceeding various UL and ASTM standards for process seals.
Benefits of Explosion Proof Wiring and Cable Bushings
Our explosion proof cable and wire bushings stand out due to the following reasons.
Enhanced crack resistance: Unlike cement-based sealants prone to cracking and fatigue, our UL 1203 Ethernet cable bushings utilize epoxy seals. These seals exhibit exceptional resistance to mechanical and environmental stresses, eliminating the need for compromising wire-and-cable product choices.
Combined explosion and process seal: In addition to safeguarding against sparks, flames, and dust, our UL 1203 bushings for cables and wires provide a hermetic process seal. With leakage rates as low as <1×10-9 cc-He/sec, they can withstand application pressures up to 10,000 psi and burst pressures exceeding 15,000 psi. This eliminates the need for separate seals in pressurized environments.
Simplified electrical system design: Simplify your electrical system design in hazardous locations with our reliable and efficient UL listed explosion-proof wire bushings. You can see various examples of products that integrate various wire and cable types with or without armored jackets, as well as hermetic solutions that are customer-specific designs added to our certification file or yours.
Applications of Explosion Proof Electrical Wire Bushing
Our explosion-proof electrical wire bushings are designed for use in hazardous-atmosphere applications in hazardous environments. Some common applications of explosion-proof cable bushing include:
Alternative energy fuel systems
Analytical instrumentation
Compression equipment
Control panels
Cryogenic systems
Gas engines and turbines
Fiber optic communications
Marine equipment, sensors and transducers
Upstream wellhead monitoring equipment
ATEX / IECEx Ex-proof Cable Bushings
Douglas offers cable bushings certified to ATEX and IECEx Ex d flameproof standards. You can integrate ATEX and IECEx rated wires and cables directly into a sealed ex proof cable assembly. Our line bushings can be directly integrated into instrumentation and flameproof enclosures, simplifying installation without sacrificing agency approvals.
You can contact our factory to explore the possibilities of designing our hermetic sealing capabilities into your specific electrical cable bushing and electrical circuit designs. By gaining hazardous area rating and quality standards (QAR/QAN), Douglas can streamline the process to a customized approved solution for OEM applications.
