It is tested strictly according to GB3906 and IEC298, thus ensure effectively the safety of equipments and operation personnel. Outline dimensions and weight 外形尺寸 Outline dimensions高度a （mm） 2200寬度b （mm）分支母線額定電流為1250A及以下， 800/650*分支母線額定電流為1600A及以下，短路開斷電流為40kA 800分支母線額定電流為1600A及以上 1000深度c （mm） 1350/1500Height a 2200（mm） Width b Rated branching bus bar current up to 1250A，Rated shortcircuit breaking current(rms.) up to 800/650*（mm）Rated branching bus bar current up to 1600A，Rated shortcircuit breaking current(rms.) up to 40KA 800 (mm)Rated branching bus bar current over 1600A， 1000(mm)Depth c 1350/1500 （mm） 重量800~1200kg，詳細資料見表1。The basic structure of switchgear panel prises the panel itself a removing part. The panel and main ponents can see in figure 3/ panel or outgoingline panel are diagram of basic switchgear panel，there are other derivative diagram，for example ,contact panel or metering panel .in addition，There are so many diagram of the switchgear panel with stationary type load switch、（SF6）VCB truck、VC truck、Disconnect truck. The panel has two maintenance modes. That is singleface maintenance and doubleface maintenance. The detail of structure and main ponents, can reference order document. Enclosure and clapboard開關柜的外殼和隔板由優(yōu)質鋼板制成，具有很強的抗氧化、耐腐蝕功能，且剛度和機械強度比普通低碳鋼板高。當手車從運行位置向試驗/隔離位置移動時，活門會自動蓋住靜觸頭，反向運行則打開。除真空斷路器外，手車可配真空接觸器、隔離裝置和計量設備等。當電纜室門打開后，有足夠的空間供施工人員進入柜內安裝電纜（最多可并接6根）。聯鎖裝置地功能如下：A series of interlocks are provided to prevent mishandling, thus protecting both personnel and switchgear itself. The function of interlocks is following: 216。 手車在運行位置時，控制線插頭被鎖定，不能拔出。母線、緊固件和附件是單獨包裝的。 用吊車裝載Load
