Vranke Technology Co., Ltd Cases

Integrated epoxy resin casting systems for dry-type transformers under vacuum conditions. Equipped with PLC control and chamber sizes up to 2400×3200 mm, ensuring bubble-free insulation and high dielectric strength in cast coils.

Fully automated winding systems such as the GRX800/GRX1200 series, featuring long spindles (up to 1200 mm), high payload capacity (up to 500 kg), and precision control for consistent coil geometry in mass production environments.

PLC-programmable automatic machines for winding thin metal foils (e.g., copper or aluminum) into transformer windings. Capable of handling widths from 100–800 mm with controlled tension and layer insulation, ideal for high-efficiency distribution transformers.

Heavy-duty winding equipment for low-voltage (LV) power transformer coils, supporting coil weights up to 3 tons and adjustable center distances (600–3500 mm). Speed is variable (0–100 RPM), enabling flexible winding of rectangular or round conductors.

Precision slitting lines for silicon steel, copper, and aluminum strips with thickness ranges from 0.15–1.0 mm. Features include high-speed operation (up to 150 m/min), tension control, and models like the 300/500 Type for clean, burr-free edge slitting in electrical steel processing.

Robust assembly tables with load capacities of 5–10 tons, engineered for precise stacking and alignment of laminated transformer cores. Suitable for multi-column core structures with maximum core sizes up to 2000×1800 mm and adjustable working heights (e.g., 1000 mm).

High-precision, high-speed cutting machines designed for processing silicon steel sheets used in transformer cores. These CNC-controlled systems support various cutting widths (e.g., 25–300 mm or up to 3000 mm) and thicknesses (0.23–0.35 mm), offering automated center-leg cutting lines for efficient ...

A leading transformer manufacturer in Southeast Asia recently partnered with Vranke to modernize its production line.
