Material: At present, stainless steel has 201 and 304 two materials, the thickness of 1mm and 0.8mm, the thickness of the heat shrink pipe 10kV not less than 1mm; 35 kV not less than 2mm (generally 15 kV-20 kV). The difference between high voltage heat shrink pipe and low voltage heat shrink pipe is mainly reflected in the voltage insulation level, high voltage heat shrink pipe usually refers to the heat shrink pipe with a voltage resistance of 10KV and 35KV, low voltage heat shrink pipe refers to the heat shrink pipe with a voltage resistance of 600V and 1KV.
Size: the customer needs to provide drawings. The smaller the arc in the four corners, the R, the better. Now the upper and lower tolerance of R6 steel strip is generally controlled at 0.2, the upper tolerance is the length controlled at + 0.2, and the lower tolerance is the length controlled at-0.2 (according to customer demand). Process: adopt fully automatic and semi-automatic production process. Welding method: for lap welding, welding 6 points are triangular and the tensile force is 25 kN.
Note: To compare the size and technical requirements of the drawing, focus on the pressure and insulation of the steel belt, and the smaller the inner arc of the four corners, the better.
