Product Description

          High-voltage wall-piercing sleeve is suitable for insulation and support of power plant and electrical appliances with an AC voltage of 35kV or lower, which is used as guiding power part through the wall or other grounding material. The casing is suitable for environment temperature of-40 ~ + 40 ºC. It is not suitable for use in the condition of reducing the casing performance and the condition of the inner part of the casing household surface condensation. When the ambient temperature of the casing is above + 40 ºC, but not above + 60 ºC, the operating current of the casing is recommended to be reduced by 1.8 % for every 1 ºC increase in ambient temperature. When the casing environment temperature is below-40 ºC and the maximum allowable heating temperature specified in section 5.1 of GB12944.1 is met, the operating current is allowed to be overload for a long time. It is recommended to increase rated current load by 0.5 % for every 1 ºC decrease in ambient temperature, but the added value should not exceed 20 % of rated current.
The casing can be divided into five types according to the place of use: indoor common type, outdoor common type, outdoor type, outdoor type, outdoor-indoor high prototype and outdoor type.
The common type is generally suitable for the installation site within 1000 M above sea level.
The common type of outdoor home is generally suitable for the area with an installation site not exceeding 1000M above sea level, but the installation site should be a no-obvious area.
The outdoor indoor anti-fouling type is suitable for installation site not exceeding 1000M above sea level. For severe and heavy fouling area, 63kV oil paper capacitive perforating wall casing can be used.
The outdoor high prototype is suitable for the installation site below 3000 M.
An outdoor interior plateau anti-fouling type is suitable for the installation of the site below 3000m above sea level in the filthy area.
The casing can be divided into three types: aluminum conductor, copper conductor and non conductor(busbar type) according to the conductor material used .
