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.
TECHNICAL DATA: The inner surfaces of breakout boots are covered with a layer of hot melt adhesive. Working temperature: AKB: from -30°C to +135°C, AKR: from -40°C to +120°C, AKF: -30°C to +135°C. Shrink temperature: > +125°C. Elongation at break: minimum 300%. Resistivity cross section: AKB: minimum 1013 µcm, AKR: minimum 1012 µcm, AKF: minimum 1013 µcm. Non-corrosive in contact with copper. UV resistant. Resistant to creepage currents (red boots - AKR). Dielectric strength: minimum 10kV/mm. Resistance to heat stroke: no cracking or material flow (measured for 4 hours at +250°C). Aging thermal properties: no cracking or material flow (measured during 500 h at +120°C). Standard colours: AKB, AKF: black AKR: red
