KTPND 25-250-10(6) U1 Transformer Substation for Oil Production
Complete transformer substations for oil production, outdoor type, are designed to receive 50 Hz industrial-frequency power at 10(6) kV, convert it to 0.4 kV, and supply it to oil production wells and other industrial facilities in temperate-to-harsh climate regions (from −45°C to +40°C).
The KTPND is supplied complete with a high-voltage disconnector, installed on the nearest power-line pole. The HV input to the substation is overhead; the outgoing 0.4 kV lines are cable-connected. Interlocks are provided to ensure safe operation by service personnel.
