GCK C-profile Assembly Economical Switch Cabinet

The GCK C-profile assembly Economical Switch Cabinet is a low-voltage (up to 690V) enclosed switchgear using a bolted C-profile steel frame. C-profiles are cold-rolled, pre-punched galvanized steel channels with a 25mm modular hole grid, enabling assembly without welding or special tools.

What does this product do?

● Power distribution – Safely delivers power from main incoming source to feeders, motors, lighting panels, and other loads.

● Drawer functionality – Houses withdrawable drawers (circuit breakers, contactors, soft starters) that can be swapped while the main busbar stays live, minimizing downtime.

● On-site reconfiguration – Easily add or move sections by unbolting end plates, bolting on new cubicles, and extending busbars with simple kits.

● Protection & isolation – Provides mechanical interlocks, shutters, and configurable form of separation (Form 2b, 3b, or 4b).

Customization Options

In essence, this cabinet offers modern draw-out switchgear functionality — safe maintenance, high density, and modularity — at an entry-level price. It is ideal for small to medium industrial plants, commercial buildings, infrastructure projects, and budget-conscious retrofits where quality cannot be compromised.

Product Parameters (Specification)

Below are the key technical specifications for the GCK C-profile assembly Economical Switch Cabinet. Values are based on standard configurations and may be customized for specific project requirements.

Product Features and Applications (Q&A Format)

The GCK C-profile assembly Economical Switch Cabinet stands out because of its unique combination of economy, flexibility, and proven performance. Below we answer the most common questions customers ask about its features and suitable applications.

Q1: What makes the C-profile design more economical than welded switchgear?

A: Three reasons: (1) Bolt-together frame eliminates expensive welding fixtures. (2) Pre-punched 25mm grid removes custom drilling. (3) Damaged profiles can be replaced individually, not the whole frame. When you purchase the GCK C-profile assembly Economical Switch Cabinet, you pay for value, not over-engineering.

Q2: Is the bolted structure strong enough for industrial environments?

A: Yes. Properly torqued (M8:18Nm, M10:35Nm), it meets IEC 61439-2 and withstands 50kA short-circuit forces without permanent deformation. For extreme vibration (e.g., stamping presses or ships), we recommend our welded MNS series. For 95% of industrial/commercial sites, the GCK C-profile is more than adequate.

Q3: How does galvanized finish compare to powder coating?

A: Hot-dip galvanizing after punching covers all surfaces — cut edges and holes included — with a uniform ≥65μm zinc layer. It won't chip or corrode when moisture seeps behind it, outperforming powder coating in humid environments (e.g., water treatment, textile mills). If color is required, powder coating can be applied over the galvanized layer.

Q4: What are the most common application scenarios?

A: Based on thousands of global installations, the GCK C-profile assembly Economical Switch Cabinet is most frequently deployed in:

Small and medium industrial plants: food processing, plastic molding, metal fabrication and textile mills

Commercial buildings: shopping centers, hotels and office buildings

Water and wastewater treatment: pump stations, irrigation and desalination systems

Retrofit projects: replacing old fixed switchboards with modern draw-out switchgear

Temporary power installations: construction sites, mining camps and event power systems

Production Details & Competitive Advantages

Production Details – How We Build the GCK C-profile assembly Economical Switch Cabinet

At Lugao Power Co., Ltd., we manufacture every GCK C-profile assembly Economical Switch Cabinet with consistency, durability, and ease of assembly.

1. C-profile manufacturing: Japanese-standard Q235B 2.0mm steel coil → CNC punch 25mm grid → cold-form C-shape (±0.3mm accuracy) → cut to length → hot-dip galvanized (≥65μm, ASTM A123).

2. Drawer cradle: 2.5mm galvanized steel with positioning dimples and nylon rollers. Accepts 8E/2 to 24E drawers via adapter plate. Three-position mechanical interlock (connected/test/isolated) with padlock hasp.

3. Drawer unit: 1.5mm steel front panel, RAL 7035 powder coating, laser-engraved label. Handle with O/I indicator. Primary contacts: silver-plated copper (≥10μm), spring-loaded tulip design. Secondary wiring: 2.5mm² PVC copper wire with numbered ferrules. Factory tested for continuity, insulation, and mechanical operation.

4. Busbar system: ETP copper (98% IACS), silver-plated joints torqued to 35–40Nm. Busbars supported every 500mm (tighter than typical 800mm). Vertical busbars connect via bolted copper links.

5. Assembly & testing: Torque-controlled assembly. Each unit tested: dielectric (2.5kV/1min), continuity, mechanical interlock, and temperature rise at 1.1x rated current. Factory test report included.

After-Sales Service – One-Year Warranty
