Overview
The GTB power frequency dry-type test transformer is particularly suitable for on-site testing of insulation performance, DC withstand voltage, and leakage testing of various electrical equipment in power systems and various power users. It is a product that replaces the current bulky oil immersed transformers.
Product Details
I. Overview
GTB power frequency dry-type test transformerIt is a new process and material that introduces foreign technology, utilizes advanced production equipment, and adopts coil epoxy vacuum casting molding and CD type iron core. Compared with oil immersed test transformers of the same capacity and voltage, it has the advantages of light weight, small size, beautiful appearance, stable performance, easy to use and carry, no oil leakage, etc., and effectively weakens magnetic leakage, improves insulation strength and moisture resistance. Specially suitable for on-site testing of insulation performance, DC withstand voltage, and leakage testing of various electrical equipment in power systems and power users, it is a product that replaces the current bulky oil immersed transformers.
