3M Terminal Protector TP 500 Right Angle Boots

Product Details

The 3M Terminal Protector TP 500 Right Angle Boot is a specialized insulating barrier system designed to provide Phase-to-Phase and Phase-to-Earth insulation for power cable terminals. These "push-on" boots are primarily used in extremely compact areas where standard clearances are insufficient to prevent electrical flashovers. Applications and Use CasesThese boots are engineered for medium-to-high voltage indoor electrical equipment. Target Equipment: Commonly installed in motor terminal boxes, ring main units (RMU), and distribution transformers. Clearance Protection: Specifically designed for operations where phase-to-phase or phase-to-ground clearance is less than 10mm. Cable Compatibility: Suitable for a wide range of cable sizes, typically from 25 sq mm up to 300 sq mm, though some variants accommodate up to 630 sq mm. Voltage Range: Rated for high-voltage applications, frequently used for 11 kV RMU systems.  Key Specifications and MaterialAccording to product data from 3M and authorized distributors like Amar Radio: Material: Injection-molded from high-quality EPDM or Silicone rubber, which provides excellent non-tracking and dielectric properties. Dielectric Strength: Rated at 15 kV/mm. Temperature Range: Operates effectively between -40°C and +130°C. Current Rating: Typically supports a current range of 250A to 1250A.  Design and Kit ContentsThe right-angle design allows for secure connections in tight spaces while ensuring easy access for maintenance.  Components: A standard TP-500 KIT typically includes an insulating bellow and grommets. Versatile Installation: Can be installed over various termination types, including pre-moulded and heat-shrink terminations. Maintenance: The boots can be easily opened and re-closed, allowing for periodic inspections of the terminal connections without needing to replace the insulation.
