产品结构及其特点Product structure and its characteristics
开关设备由柜体和中置可抽出部件(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护等级为IP2X。具有架空进出线 申维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。
Switchoear consists of two maior parts: cabinet and withdrawable intermediate components .e. handcart). Cabinet is divided into fou separate compartments. Protectiongrade of enclosure is P4X: protection grade is 1P2X when doors of cubicle exterior and circuit breaker chamber are open. Since the switchgear alows instalation,commisioning and maintenance rom ts front, t can be placed back-to-back to form dua-arangement and be instaled aainst a wal, mproving ts safety and flexibilityand reducing floor coverage.
