Valve electric motors with three-wire supply line,

Synchronous valve submersible oil-filled motors of VPED series in 81 mm dimension with three-wire power supply line, climatic version B, placement category 5 according to GOST 15150 and GOST 15543, designed for continuous mode S1 according to GOST IEC 60034-1. Motor control is performed from the valve motor control station with a three-wire power supply line (with an implicit rotor position sensor); the mains voltage should be 380 V ± 15% and the mains frequency 50 Hz ± 1%. Depending on the configuration, which includes the electric motor the installations are divided into:

• - Units of the 3rd dimension (ESP with 81 mm casing diameter), in which a protective pad is installed on the head of the ESP with 81 mm casing diameter, to protect the cable extension during downhole lifting operations (RLO). The described diameter of the head is 93.5 mm (hereinafter referred to as "3-gauge rig");
• 2A-size units (ESP with the casing diameter of 69 mm), in which the...
