Heat-shrinkable breakout boots for medium voltage up to 36 kV, red color AKR 4 TKP3K135566428D1

AKR (red), AKB and AKF (black) heat shrink breakout boots are mainly intended for sealing the place where cables exit from the mechanical sheath (plastic or metal pipes) mounted on a medium voltage overhead line pole. The breakout shrunk on the cables protects against the penetration of: water, dust, insects and other impurities into the casing pipe. Breakout boots are designed for low and medium voltage cables. Long-term and reliable operation of breakout boots is ensured by resistance to UV radiation, aggressive chemical agents and creeping currents. Made of high-quality cross-linked polymer, thanks to which they are resistant to creeping currents and erosion (anti-tracking). They have excellent insulating and sealing properties.
