CMTI consists of a MV distribution unit for connecting with the electrical distribution net, an electric meters panel, invertor modules with the necessary power to convert the energy coming from the solar batteries, a LV panel with a collecting busbar system, and an appropriate power transformer.
•    CCTPs are modern products, intended for voltage 0.32 or 0.4/(10)20 kV, as well as for transformers with rated power up to 1600 kVA.
•    CCTPs are used for connection with the electricity distribution net of photovoltaic power stations.
•    CCTPs are intended for open air installation, at temperatures between - 30° to + 40° and altitude above sea level below 2000 m.
•    The structure is made of steel sections, covered outside and inside with Maglite plates that guarantee 4 hours fire resistance. The doors and lattices are made of eloxated aluminium sections and eloxated aluminium sheets and etalbond.
•    CCTPs are with outside servicing, what allows easy substitution of the installed equipment when necessary.
•    The whole equipment is jointly earthed.
•    The CCTP's dimensions depend on the power and type of the employed invertors.
•    CCTP meets the requirements of standard BDS EN 62271 – 202:2007 and the Regulation on the layout of electric systems and electricity conducting lines.
