100 kV 5 kVA Gas-Insulated AC Withstand Voltage Test Transformer: Five Key Selling Points Empowering Insulation Testing

info-734-726

In the field of high-voltage equipment insulation withstand voltage testing, "bulky equipment, cumbersome maintenance, and significant susceptibility to environmental factors" have long been pain points in on-site testing. Goldhome's 100kV 5kVA gas-insulated AC withstand voltage test transformer utilizes SF6 gas insulation technology. With its outstanding advantages-including lightweight design, maintenance-free operation, and interference resistance-it has become the ideal choice for testing the insulation strength of electrical equipment such as cables, switchgear, and transformers.

 

Core Selling Point 1: Lightweight-40%–65% lighter than oil-immersed models, making on-site operations effortless and convenient

Traditional oil-immersed test transformers are bulky and heavy, making transportation and on-site handling extremely inconvenient. This product uses SF6 gas insulation, reducing weight by 40%–65% compared to oil-immersed equipment of the same rating, allowing a single person to move it with ease. Upon arrival, there is no need to wait for the unit to settle; testing can begin immediately after power connection. This makes it particularly suitable for operations requiring frequent relocation, such as on-site inspections by power utilities and emergency repairs at substations.

 

Key Selling Point 2: Cost-Effective - Maintenance-Free Design, Requires Gas Recharge Only Once Every Four Years

Oil-immersed transformers require regular testing of insulating oil and replacement of aged oil, making maintenance cumbersome and time-consuming. This product uses SF6 gas insulation, completely eliminating the hassles of oil contamination and routine oil maintenance. SF6 gas (approximately 0.05 MPa) needs to be replenished only once every four years, resulting in extremely low long-term operational costs-saving time, effort, and providing peace of mind.

 

Core Selling Point 3: Stability - SF6 Gas Insulation Ensures Consistent Performance Unaffected by the Environment

The insulating properties of mineral oil are significantly affected by temperature and humidity, leading to fluctuations in extreme environments. SF6 gas possesses extremely high dielectric strength, offering superior insulation performance compared to traditional oil-immersed transformers, and is unaffected by climatic conditions. The equipment is factory-set to an operating pressure of 0.2–0.25 MPa; when the pressure drops to 0.19 MPa, it automatically replenishes the gas, ensuring long-term stable operation.

 

Core Selling Point 4: Robust - Multiple Safety Protections, Precise and Reliable Testing

With a rated output of 100 kV/5 kVA, a high-voltage current of 50 mA, and a voltage ratio of 1000:1, the equipment is equipped with multiple protection mechanisms, including overvoltage and overcurrent protection. The temperature rise is only 10℃ within 30 minutes, ensuring stable and reliable operation. Voltage measurement accuracy reaches 0.5% FS ±3 digits, and current measurement accuracy is 0.5% FS ±3 digits, delivering accurate and reliable test data.

 

Core Selling Point 5: Versatility - One Machine, Multiple Uses, Suitable for Various Testing Scenarios

This product is widely applicable for power frequency AC withstand voltage tests on various power equipment, including cables, GIS, switchgear, transformers, and generators. It meets the needs of multiple scenarios, such as factory acceptance testing for new equipment, pre-commissioning inspections, periodic preventive maintenance, and post-failure troubleshooting. As a national-level high-tech enterprise, possesses years of experience in the R&D and manufacturing of high-voltage testing equipment. Our products strictly comply with industry standards such as DL/T 848.2-2018, and we offer a three-year warranty and lifetime maintenance services to ensure users have complete peace of mind.
