Insulating Bushing System Benefits
Insulating bushings are essential components in professional electrical installations, providing critical protection that standard locknut and bushing combinations cannot match. The insulated throat design eliminates the risk of conductor damage from sharp conduit edges while ensuring electrical isolation between the grounded conduit system and live conductors. This protection is especially important in large conduit sizes where conductor installation forces are higher and the risk of insulation damage increases significantly.
Why Choose High-Temperature Plastic Construction?
The 105°C temperature rating of this plastic insulating bushing makes it ideal for applications where elevated temperatures are present, such as near transformers, motors, or in high-ambient temperature environments. Unlike standard plastic bushings, this high-temperature design maintains its structural integrity and insulating properties even under thermal stress, ensuring long-term reliability in demanding electrical installations. The lightweight plastic construction also reduces installation fatigue while providing the same level of protection as heavier alternatives.
