Flame Retardant Heat Shrink Right Angle/In-line Bushing Boot
Heat Shrink Right Angle/In-line Bushing Boots are specialized electrical accessories used to provide insulation and sealing for cable terminations at right angles or inline connections. These boots are designed to protect cable terminations from moisture, dust, and other environmental contaminants, ensuring proper insulation and preventing electrical leakage.
• Manufactured from polyolefin,inner coated with hot-melt adhesive at the ends
• Excellent insulation,flame retardant,thermal stability,etc
• Used to protect cable against flashover or surges induced in switchgear and transformer
• Shaped components to meet arange ofrequirements
These bushing boots are commonly used in a variety of electrical applications, including power distribution systems, transformers, switchgear, and outdoor cable connections. They are particularly useful in areas where cable terminations are exposed to harsh environmental conditions, such as heavy rain, high humidity, or extreme temperatures.
