Product Description

                 The casing is made of porcelain, mounting flange and conductor. The busbar through the wall sleeve does not have the conductive part, the ceramic cover and the flange fix way except 35 kV high prototype and some products use the mechanical clamping, the other other uses the cement cement cement adhesive to install; The copper conductor is fixed by the center washer and the nut, and the copper and aluminum conductive row is fixed by the center washer and the opening pin. The opening size of busbar through the wall Bushing ends is determined according to the selected busbar specification type. The surface of the accessories is coated with gray paint.In order to improve the initial corona of the casing, the ceramic wall near the flange and the umbrellas(edges) on both sides are increased and thickened, and the first umbrellas(edges) close to the flange are evenly coated on the inner cavity and flange of the ceramic cover before roasting, and the first umbrellas(edges) close to the flange are burned and the semiconductor glaze is firmly bound to the wall. By short circuit the ceramic wall, the electric field distribution is greatly improved, the discharge in the casing cavity is prevented, and the voltage of the flash discharge is increased.
            The conducting part of the casing is made of aluminum conductor, which saves a lot of copper material and reduces cost. The increase of the conductive area connected to the busbar oversolves the disadvantage of the small contact area of the copper guide rod.
       The sleeve mounting flange is divided into two kinds of installation methods, except 6, 10 kV copper conductor pipe fitting, the others are reverse loading.
          1. Types and patterns
Depending on the location of the installation, the interior type and shape of the house may be selected, with conductors for the purpose and without conductors for the mother
Linear wall casing. Aluminum conductors are usually used in house electrical distribution equipment.
      2. Selection of rated voltage
The rated voltage sulfoxide according to the wall-piercing casing shall not be lower than the rated voltage of the grid in which it is located. When there is ice and snow, 3 ~ 20kV outside the wall casing should be selected a higher voltage products. For 3 ~ 6 kV, it is also possible to adopt products that increase the two-stage voltage.
         3. Selection of rated current
The rated current of a wall-piercing sleeve with a conductor shall not be less than the maximum continuous operating current of the circuit. The busbar itself is free of conductors and has no rated current selection problem but should be checked for busbar size allowed through the window .
