## ****Product Introduction****

![switchgear temperature rise test set](https://demikspower.com/wp-content/uploads/2026/10/switchgear-temperature-rise-test-set-225x300.jpg)

The [**6300A Three-Phase Temperature Rise Test System**](https://demikspower.com/switchgear-test-equipment/full-automatic-temperature-rise-test-system/) is a high-power high-voltage electrical testing equipment independently developed and manufactured by Shanghai Demiks Power Technology. The complete system consists of **three-phase oil-immersed induction voltage regulators, high-current booster (3-phase output A/B/C), intelligent main control cabinet, flexible copper braided high-current leads and multi-point temperature data acquisition unit**. It is specially designed for [switchgear temperature rise type tests](https://demikspower.com/switchgear-test-equipment/full-automatic-temperature-rise-test-system/) on high-current carrying components such as switchgears, busbars, circuit breakers, disconnectors, contacts and copper bars.

The system can continuously output rated three-phase current up to 6300A with stable current output and high three-phase current balance. It adopts oil-immersed self-cooling induction voltage regulation structure with strong overload capacity and controllable temperature rise under long-time full-load operation. Equipped with intelligent control system, it supports automatic voltage & current stabilization, real-time multi-point temperature collection, curve recording and over-limit protection. It can run steady-state temperature rise test for extended periods and fully comply with domestic and international standards including GB/T, IEC and ANSI for power equipment testing.

## ****Application & Purpose****

This 6300A three-phase high current temperature rise test equipment is used to perform **long-duration current-carrying temperature rise type tests** for medium & high voltage switchgears, complete power distribution assemblies, bus ducts, vacuum circuit breakers, disconnectors, earthing switches, terminal lugs, copper bars and contact assemblies.

1. **Type Test Verification**: Verify the temperature rise of conductive parts (contacts, busbars, terminals) under rated continuous working current of 6300A, check compliance with GB, IEC and ANSI temperature limit requirements, and validate conductive loop design and contact reliability.
2. **Factory Routine Test**: Switch-gear manufacturers and electrical assembly factories use this equipment for sampling inspection of thermal performance under high current before product delivery, to detect hidden risks such as poor contact, insufficient busbar sizing and assembly defects in advance.
3. **Research & Third-Party Testing Institutes**: Power research institutes and quality inspection laboratories use the system for R&D testing of high-voltage distribution equipment, third-party authoritative inspection and new product certification tests.
4. **Test for Converter Cabinets & High-Current Complete Equipment**: Suitable for temperature rise verification of large-capacity AC switchgears matched with DC systems, high-current busbars and metal-enclosed switchgear assemblies.
