Heat Shrinkable Straight Boot :
Heat Shrink Straight Boots provide insulation to the bushings in the cable termination box, where the clearance between phase to phase and phase to earth is less than the normal air clearance. These boots provide protection against flash over in the event of high humidity, rodent menace and surge impulse. The boots are mode from high quality cross linked non tracking polyolefin material. They are internally coated with water resistant red mastic.
| Characteristics |
| This data sheet covers the requirements for heat shrink medium voltage boots whose dimensions will shrink to predetermined size upon the application of heat above 125 deg. C. Color of the MV boots is reddish brown. The MV boots are electrically insulating, anti-tracking, UV resistant, weather proof and flame retardant. Both ends of MV boots are internally coated with red mastic and covered with release paper. |

| Typical Applications |
| The MV Straight Boots provide insulation and sealing for bushings in cable-end boxes integral with switch-gear and transformers. The mastic sealant provides a water-tight environmental seal to the bushing. The MV boots are also supplied as a part of heat shrink cable termination up to 36 kV for operation in air-filled cable-end boxes, designed with reduced clearances for compound filling. The boots are designed to withstand surges induced during the operational life of the termination. |
