Product Description
Prevent electric shock and short-circuit caused by foreign matters: It wraps live metal terminals to avoid short circuits triggered by bridging of small animals or debris, and protects maintenance staff from accidental live contact.
Waterproof and moisture-proof: Made of silicone rubber with outstanding hydrophobicity, it stops rainwater from forming a water film on terminal surfaces and prevents flashover discharge induced by dampness.
Increase creepage distance: Designed with alternating large and small sheds inside to effectively extend creepage distance and improve anti-pollution flashover performance.
Important Notes
Color classification for application: Yellow or green boots apply to earthing side (low-voltage end); red boots are used for high-voltage incoming terminal.
Difference from heat shrink tubing: The protective boot is detachable and reusable for frequently maintained equipment; heat shrink tubing realizes permanent sealing for long-term fixed protection.
In summary, such terminal covers greatly improve the operation safety of transformer high-voltage terminals and reduce circuit tripping risks arising from contamination and damp conditions.
Excellent weather resistance: Silicone rubber resists UV and ozone ageing, ensuring stable long-term service within the temperature range from -50℃ to 200℃.
Hydrophobic & self-cleaning property: Dirt hardly adheres to the surface; contaminants can be washed away by rainfall, ideal for heavily polluted outdoor working conditions.
High tear resistance: Superior toughness compared with conventional heat shrink tubes, effectively preventing cuts caused by metal burrs during installation.
