☷ Product Description
The JBK5 series transformer is a new generation of energy-saving machine tool control transformer, widely used in various metal cutting machine tools, forging equipment, etc., to provide power for control circuits, work lighting, and indicator signals of machine tools.
▶ Core Material: Made of high-quality cold-rolled silicon steel sheets with high magnetic induction and low loss, effectively reducing iron loss (no-load loss) to ensure high efficiency, energy saving, and low temperature rise.
▶ Winding Process: Utilizes all-copper or electrolytic copper windings with excellent electrical conductivity and low load loss. The coils are precision-wound and vacuum-impregnated with insulating varnish, resulting in a robust structure with strong short-circuit resistance and weather durability.
▶ Insulation and Protection: Adopts insulation systems from Class A (105°C) to Class F (155°C), offering excellent electrical and mechanical strength. Various enclosure options are available, including open type (IP00), protected type (IP20), and fully enclosed type (IP54), to suit different installation environments.
▶ Cooling Method: Depending on capacity, uses natural air cooling (AN), forced air cooling (AF), or oil-immersed cooling to ensure proper heat dissipation.
☷ Product Advantages
▶ Energy Efficient: Utilizes high-quality cold-rolled grain-oriented silicon steel sheets with low core loss. Compared to older transformer models, it effectively reduces electrical energy loss, improves energy utilization efficiency, and aligns with the trend of green and energy-saving development.
▶ Compact and Lightweight: Optimized magnetic circuit design and winding arrangement result in a volume reduction of approximately 20% - 30% compared to traditional machine tool control transformers at the same capacity. The reduced weight facilitates installation and handling while saving internal equipment space.
