The transmission line poles are made of spun reinforced concrete with circular cross-section and with cone like form. For low voltage 0.4KV, heigh voltage 10KV, 35KV and 110KV, and for mixed transmission lines 10KV-0.4KV.
The height of the poles is changeable and can be from 9m for 0.4KV, 12m for 10KV and 14-21m for 35KV and 110KV.
All poles are equipped with brackets and rings for stiffening as well as all necessery nuts for earthling.
The poles are made as standard(bearing) and angle for 20, 40 and 60(special) degrees.
The foundation of the transmission line poles is carried out with sport footings under every pole.
For reconstruction of the existing wooden lines and construction of new, used are reinforced concrete trestles type "Karpos".
The factory "Karpos" S.C. Skopje undertakes erection of all types of transmission line poles and construction of all above mentioned lines.


SUB_STATIONS

The reinforced concrete substation type "Karpos" 10-20/0.4KV 1000KVA is constructed as a standard structure made of prefabricated reinforced concrete elements intended for distributional and industrial plants with the voltage of 10-20/0.4KV.
The structure and the form of the elements allow not only fast assembly but fast disassembly as well.
All works starting from excavation of soil, earthling protection and assembly of the elements can completed in 3 days when the structure becomes ready for installation of the equipment.
The reinforced concrete sub-station type "Karpos" 35/10KV are made of prefabricated reinforced concrete elements joined among each other in a way that needs minimal time of erection.
The basic purpose of the structure is to receive equipment 35/10 KV and provide room for other necessery premises.
This flexible system gives a possibility for construction of many different structures with continuous change of their height and width.
The structure is thermicaly insulated, covered with aluminum plate, the ironmongery is made of ZP profiles. The time necessary for "turn-key basis" system is minimal.
