YDJZ, AC/DC Withstand Voltage Tester

AC/DC withstand voltage testers are primarily used to conduct insulation strength tests on various electrical products, electrical

 components, and insulating materials under specified voltages to assess the insulation level of products, detect insulation defects, 

and measure overvoltage capability.

▶They are the preferred product for power operation departments, electrical appliance manufacturers, metallurgical, coal mining, 

electrified railway departments, research institutions, and universities requiring withstand voltage testing equipment.

▶They are essential testing equipment for power equipment inspection and preventative testing.

The YDJ(Z) series lightweight AC high-voltage test transformer is manufactured based on the Ministry of Machinery and Electronics 

Industry's "Test Transformer" standard, with significant improvements over previous similar products.

This series features small size, light weight, compact structure, complete functions, strong versatility, and ease of use.

They are particularly suitable for power systems, industrial and mining enterprises, and research departments to conduct insulation 

strength tests on various high-voltage electrical equipment, electrical components, and insulating materials under power frequency or

 DC high voltage.

They are indispensable and important equipment in high-voltage testing. The power frequency withstand voltage test device adopts 

a single-frame core structure. The primary winding is wound around the iron core, while the high-voltage winding is on the outside.

 This coaxial arrangement reduces leakage flux, thus increasing coupling between the windings. The product's casing is made into an 

octagonal structure that fits well with the core, resulting in an aesthetically pleasing overall appearance.

The YDQ series power frequency withstand voltage test device is manufactured based on the Ministry of Machinery and Electronics 

Industry's standard for "Power Frequency Withstand Voltage Test Devices," with significant improvements over previous similar

 products.

This series features small size, light weight, compact structure, complete functions, strong versatility, and ease of use.

It is particularly suitable for power systems, industrial and mining enterprises, and research departments to conduct insulation strength

 tests on various high-voltage electrical equipment, electrical components, and insulating materials under power frequency or DC

 high voltage. It is an indispensable and important piece of equipment in high-voltage testing.

Compared to traditional oil-immersed light-duty test transformers, the gas-filled light-duty test transformer series is 20%-60% lighter

 (depending on voltage and capacity level) and eliminates oil pollution. A single test transformer can handle voltage levels up to 300KV.

Due to the adoption of new production processes, the technical performance of the product has been significantly improved, making 

it particularly suitable for field work and frequent relocation conditions.

The GTB dry-type test transformer utilizes the latest advanced foreign technology and advanced production equipment, employing a 

new process and new materials, including epoxy vacuum casting of the coils and a CD-type iron core.

Compared to oil-immersed test transformers of the same capacity and voltage, it boasts advantages such as lighter weight, smaller 

size, more aesthetically pleasing design, stable performance, convenient use and portability, and no oil leakage.

It effectively reduces leakage flux, improving insulation strength and moisture resistance. It is particularly suitable for power systems

 and various power users to conduct on-site testing of the insulation performance, DC withstand voltage, and leakage current of

 various electrical equipment.

It is the preferred new product to replace the currently bulky oil-immersed transformers. Dry-type transformers, oil-immersed 

ransformers, and gas-filled transformers are available, with capacities ranging from 1.5kVA to 300kVA.
