Product Description

The GCK-type low-voltage withdrawable switchgear is designed for three-phase AC systems with frequencies of 50Hz or 60Hz, rated voltages of 380V or 690V, and rated currents up to 4000A. It is suitable for both three-phase four-wire and three-phase five-wire power systems.

This switchgear is widely used in power plants, substations, industrial and mining enterprises, commercial buildings, hotels, airports, and ports for power distribution, conversion, control, and reactive power compensation.

Key Features

High Breaking Capacity: Excellent dynamic and thermal stability.
Versatile Configuration: Integrates Power Centre (PC) and Motor Control Centre (MCC) functions.
Advanced Structure: Technical performance matches advanced international standards.
Flexible Design: Can be configured as a combination of fixed and drawer-type cabinets.

Frequently Asked Questions

Are you a manufacturer or a trading company?

We are an integrated group company that combines R&D, manufacturing, sales, and engineering services. We own modern production facilities and our own R&D team, which allows us to maintain direct control over product quality and delivery.

What are your main products?

Our core product lines include Energy-Saving Power Transformers (dry-type and oil-immersed), Intelligent Complete Sets of Equipment (HV/LV switchgear), New Energy Equipment (PV inverters), and customized Industrial Electrical Equipment.

Do you offer product customization?

Yes, we specialize in customization. We provide tailored product design and engineering solutions based on project specifications, voltage levels, environmental conditions, and specific customer requirements.

How do you ensure product quality and reliability?

We implement a multi-tiered approach: source control of raw materials, strict ISO 9001 process control at every stage, and rigorous final testing (withstand voltage, partial discharge, and functional tests) before shipment.

Can you provide EPC (Engineering, Procurement, Construction) services?

Absolutely. We provide comprehensive EPC turnkey services for up to 220KV transmission & distribution projects, including engineering design, equipment procurement, civil works, installation, and commissioning.

What is your typical lead time?

Standard products generally take 15-30 days. For large custom-made orders or complete sets of equipment, the lead time is determined based on the specific technical complexity of the solution.
