2. Assignment:

Three-phase power transformers TME series (hermetic execution of TMEG) general-purpose, with natural oil cooling, capacity from 25 to 250 kVA, with non-excitation regulating designed to power electrical equipment excavators. Transformers meet the requirements of GOST 11677 and technical condition 5100 RK 0001 0033 AO-17-2005.

Transformers designed for operation in the conditions of shaking, vibration, impact, inertial forces during acceleration and deceleration of the turntable, heel and trim up to 120, can be located at a distance of 6 m from the axis of rotation of the platform. For provided periodic cleaning of dust transformers can work in dusty air 400 mg/m3. Transformers are not designed to work in hazardous and corrosive environment.


3. Conditions:

Height over sea level
up to 1000 m
The ambient air temperature
from −45°C to +40°C
Relative humidity
no more than 80% when +25°C


4. Working resource:

Warranty period
3 years
Full life
not less than 25 years
