Bushing Type Current Transformer
We Manufacturer Assembled & Non Assembled types of Bushing CTs.
Applications
Bushing current transformers are designed and manufactured in accor-dance with international standards and customer specifications. Generally used in power and distribution transformers in oil, gas insulated systems or air-insulated panels to measure the primary currents between 20 and 3000A.
According to the application area, crepe paper, woven polyester and polyester film, or their combination are used for their insulation. Production feasibilities based on dimension are as follows
- Inner diameter ≥ 150 mm
- Outside diameter ≤ 900mm
- Height ≤ 140 mm
- Weight ≤ 175 kg
Each Bushing current transformer is 100% routine tested in accordance to the standard which defined on its label and are reported to our clients. Transformers can be produced as a single unit or as a set by bringing together more than one unit.
The advantages of assembly set
- Easy assembly,
- All the materials are anti-magnetic
- The drying process does not require,
- Different identification application for secondary (color codes, plastic labels, etc.)
- They can be used for all measuring and protection applications.
