10KV/20KV/35KV heat shrink terminals and intermediate joints (including single core/three core models), compatible with cross-linked cables (XLPE) and oil immersed cables, covering a cross-section of 50-400mm ². IP68 waterproof (tested under 0.1MPa water pressure for 48 hours), IEC 60502-4）； Nonlinear stress control (field strength ≤ 2.5kV/mm); Long term insulation: dielectric strength ≥ 30kV/mm, temperature resistance -55 ℃~130 ℃. The weight of the propane spray gun is 1/3 of the traditional porcelain sleeve terminal (with a diameter of 120mm and a terminal weight of less than 1.2kg). It can be installed in 3 minutes per set, saving 65% of the working hours compared to cold shrinkage technology.
