Heat Cycle Test System for Power Cable Compliance Testing

Our advanced Heat Cycle Test Systems simulate real-world current loading conditions for power cables, ensuring compliance with international standards including IEC 60840, IEC 62067, and IEC 62985 for both type tests and routine tests.

System Configuration

Core Components

• Mobile high-current heating transformers

• Precision inductive voltage regulator

• Programmable IGBT regulator (for rapid voltage rise)

• Current transformers (CT) for measurement

• PLC-based control system with HMI

Testing Capabilities

• AC dielectric withstand tests

Technical Specifications

Testing Methodology

The system creates two parallel circuits:

1. Test Loop: Applies high voltage (AC/DC) through HV bushings

2. Simulation Loop: Short cable section with embedded temperature sensors

Ordering Information Required

• Total length of test cable

• Conductor material (copper/aluminum)

• Conductor cross-section area

• Insulation type and thickness

• Required test voltage levels

Safety Features

All systems include:

• Automatic emergency shutdown

• Overcurrent protection

• Temperature fail-safes

• Isolated control circuits

Custom configurations available for special cable designs including XLPE, EPR, and fluid-filled cables up to 500kV class.
