产品结构及其特点Product structure and its characteristics

1.体积小巧的24kV开关设备，本产品结构型式与12kV中置开关设备类同，用在20kV的系统中，不需要复合 绝缘，不需要加相间隔板，因此产品的绝缘水平优越

1.With its structure type similar to 12k intermediate switchgear, the 24kV switchgear features compact size and can apply to 20kV system, requiring neithercompound insulation nor partition between phases. As a result, product has superior insulation level.

2.结构安全,安装灵活开关设备由柜体和中置可抽式部件(即手车)两大部分组成。柜体分四个单独的隔室，外壳防护等级为IP4X,各小室外间和断路器室门打开时防扩等级为IP2X。具有架空进出线,电进出线及其它功能方案，经排列,组合后能成为各种方案形式的配电装置。本开关设备可以从正面进行安装调试和维护，因此它可以背靠背组成双重排列和靠墙安装，提高了开关设备的安全性.灵活性，减少了占地面积。

2.Featuring safe structur and flexible instalation,the switchgear consists of two major parts: cabinet and withdrawable interediate components (i.e. handcart).Cabinetis divided into four separate compartments.Protection grade of enclosure is P4X protection grade is P2X when doors of cubicle exterior and circuit breakerchamber are open.Possess overead incomina and outooina cables,botom incoming and outgoing cables and other functional proposal: they become powerjistributon deyices in various pronoals ater arrantind and combinino. Since the switchoear alows instalaton, commissionin and maintenance trom ts tront. it canbe placed back-to-back to form dual-arrangement and be installed against a wal, improving its safety and flexibility and reducing floor coverage
