The through core transformer is usually used to heat the conductor of the cable during the cable test (the cable conductor forms a closed loop, which is equivalent to the secondary coil of the transformer. When the through core transformer works, a large current is generated in the conductor, so as to heat the cable. Several cables can be used in parallel, and the cable can be heated for current rise test at the same time.

Application

It is applicable to cable current carrying capacity test, cable temperature rise test, bus current carrying capacity temperature rise test and conductivity and conductivity test of various metals. It can be used together with control parameter console, voltage regulator, etc. it can also be connected in parallel in turn to double the voltage to the required voltage. It has the advantages of flexibility and wide applicability. It is used by major enterprises.

Technical parameter

Input voltage: 220 / 380 / 660 (or designed as required)

Output voltage: (arbitrarily designed according to the voltage required by the test object)

The capacity is 50-75-100-125-150-200-250-315-400-500-630kva

The through core size can be designed according to the required size.

What parameters do custom transformers need to provide?

1. Rated power: output voltage × electric current;

2. Working frequency: generally 220V / 50Hz in China, which can be customized within 1000Hz

3. Output voltage: rated working voltage and no-load voltage

4. Output current: output rated working current or no-load current

5. Overall dimension: length, width and height of transformer

6. Special requirements: other special shall refer to temperature rise, efficiency, insulation grade, voltage regulation rate, wiring mode, etc.

7. Scenario usage: when designing special transformers, technical engineers need to understand the industry and working scenario in which the transformers are used, so as to design transformers that meet the user's needs
