Complete Outdoor Transformer Substations (KTP)
(设备/材料)
描述:
Outdoor complete transformer substations (hereinafter referred to as KTP) are transformer substations of a dead-end or pass-through type, used to receive three-phase alternating current electric energy with a frequency of 50 (60) Hz, voltage of 6, 10, 20 kV, convert it into electric energy with a voltage of 0.23 kV, 0.4 kV or 0.66 kV and supply it to consumers. In networks with a solidly earthed or isolated neutral. Networks with an isolated neutral are used in conditions with increased safety requirements peat developments, coal mines, mobile electrical installations and others. Kiosk-type complete transformer substations (KTP) are used at industrial facilities, in places of mineral extraction, as well as in urban and rural electric networks, in difficult conditions of the northern regions of Russia, low temperatures, heavy snow and wind loads. They have a high degree of factory readiness ensuring minimum terms of commissioning.
