Equipment

SANTOS MAQUINARIA ELECTRICA, S.L., with a constructed surface of 2,800 square meters has the most modern facilities, instruments and specialized machinery for a complete and effective winding electro-mechanical maintenance and repair of all types of electrical rotating machines,transformers, wind turbine gearboxes, geared motors and gearboxes.

• Lifting cranes of 20 ton & 5 ton and Hoist.
• Automatic Winders.
• Bake ovens.
• Balancing machines with cardan drive system up to 5 000 kg and with belt drive up to 500 Kg.
• Coil forming machine.
• Hot presses for manufacture of high voltage coils and bars.
• Electric motor test bench up to 1200 kW.
• Lathe, milling center, hydraulic press, etc.

VPI tanks:

• Vacuum pressure impregnating system. VPI 3 m high and 2 m in diameter and 1.1 m high and 0.8 m in diameter.
• Several immersion reservoirs of different sizes and shapes.

Burn off ovens:

We have a Burn off ovens to remove the failed winding without use of direct flames and high temperatures. This practice ensures the preservation of efficiency of repaired machines assuring the continuation of the electrical characteristics of magnetic stator´s core.

Test benches:

We have a test benches for load test of electric motors and generators up to 1.2 MW. The benches are equipped with dynamometers of 1200 and 580 kW each. Following tests can be performed:

• DC motors.
• AC high and low voltage electric motors.
• AC Generators.

We can carry out routine test and tests in accordance with the UNE, IEC and IEEE standards, as well as vibration analysis. We can provide reports and other test protocols under request.

Additional equipment:

• Laser alignment tool
• Surge and high voltage tester
• Micro Ohmeter for measuring very low resistances.
• AVO Megger, insulation measurement up to 5 KV
• EDA III insulation analyser
• Dielectric strength testers.
• Oscilloscope.
• Surge and HIPOT tester output voltage 24 kV.
• TAN DELTA TEST SET insulation measurement up to 12 kV, adjustable from 250 V to 12 kV for tan delta testing.

We also have a variety of Meggers, multimeters, clamps, tachometers, micrometers, calipers, torque wrenches, tooling, hand tools, so on.
