Technical Specifications

Performance Characteristics

Advanced Insulation System

Designed to withstand 1.1 times rated voltage for 1 minute with partial discharge levels below 5pc at 700kV. The insulation system accounts for thermal expansion/contraction of oil.

Robust Overload Capability

• Operates at 120% current (8.4A) for 300s without winding damage

• Withstands 110% voltage (330kV) for 60s without insulation damage

Extended Operational Capacity

• Continuous operation at 100% rating for 60 minutes

• Unlimited operation at 75% of rated voltage and current

Innovative Design Features

Precision Engineered Core

Utilizes grain-oriented electrical steel (130-0-130) with chip-removal treatment and curing agent integration for reduced noise and enhanced durability.

Adjustable Reactance System

Features iron core structure with adjustable air gaps between coils. Includes guide rails ensuring precise vertical/horizontal movement of iron coils.

Thermal Management

Pedestal design accounts for heat from high-intensity magnetic fields. Stainless steel brackets minimize eddy current losses that could affect quality factor.

Reliable Grounding

Incorporates grounding baffles between winding and inner coil for secure, reliable earthing.

Application Advantages

Long Service Life

Engineered for operational lifespan exceeding 60 years through optimized materials and construction.

Precision Tuning

Load capacitance adjustment range of 11-89nF (including capacitance voltage divider) enables precise system matching.

Research-Backed Design

Developed in collaboration with leading universities and research institutes for continuous quality improvement.

Industry-Leading Performance

The HCRS series represents the forefront of power frequency variable resonant systems, incorporating proprietary improvements over conventional designs. Our abandonment of outdated structures and implementation of innovative solutions results in superior performance for high-voltage testing applications.
