the switchgear itself. This paper describes the design and the main specifications of a new generation of indoor MV switchgear. Innovative ring main unit design for safety and availability by Alex Pikkert and Gerard Schoonenberg, Eaton Holec, Netherlands Fig. 1: 24 … 11kV Ring Main Unit Product Details: General. Electric ratings: system voltage 12kV, rated current upto 630A, AC50HZ-60HZ. Especially it is suitable in power supply load density greatly and the industry business zone or rural area villages and towns of cable feed network .At the same time RUM is safety in use, not bullied waits influence, installs easy, keeps in repair few and save place

A Compact Switchgear Solution for Secondary Distribution (Ring Main Unit Up to 24kV, SF 6-Insulated) RMU Susol RMUis enable to install on medium voltage distribution network and mainly used for protection of transformers in compact substations. the main beam of the array of x-directed short dipoles lies along the y-axis. The nulls of the array element pattern along the x-axis prevent the array from radiating efficiently in that broadside direction. End-fire arrays may be designed to focus the main beam of the array factor along the array axis in either the =0o or =180o directions

A ring-main unit is a piece of switchgear used on high-voltage distribution ring-main systems (e.g. in the UK at 11 kV). Essentially, it's three switches incorporated into one device used to CYCLOALKANES, CYCLOALKENES, AND CYCLOALKYNES any important hydrocarbons, known as cycloalkanes, contain rings of carbon atoms linked together by single bonds. The simple cycloalkanes of formula (CH,), make up a particularly important homologous series in which the chemical properties change in a much more dramatic way with increasing
