Product Description
Product Introduction
This series of products adopts a three-dimensional wound core component. After assembly and annealing, the three-phase magnetic circuit is completely symmetrical, the magnetic resistance is greatly reduced, and the excitation current and no-load losses are significantly reduced. The upper and lower clamps are integral, protecting the entire core from external forces during manufacturing, transportation, and installation. With pressure clamping and supporting coils, it improves the ability of the transformer to withstand axial electromotive force during a sudden short circuit. The steel structure clamp effectively suppresses noise oscillation within the clamp, keeping the transformer noise in an ideal state. The epoxy resin coil conductor and resin insulation layer form a complete rigid body, with good mechanical properties and strong short-circuit resistance. The high withstand voltage strength of the epoxy resin and the fact that the entire coil conductor is encapsulated by the epoxy resin solid insulation layer make it difficult for moisture to permeate. It completely prevents the conductor from being damaged by various harmful substances and corrosive chemicals, providing strong moisture and dirt resistance, making the product safer and more environmentally friendly. With low no-load loss, low excitation current, low noise, small size and light weight, it is widely used in high-rise residential buildings, airports, docks, subways, hospitals, power plants, metallurgical industries, shopping malls, densely populated areas, and petrochemical plants, nuclear power plants, etc.

Product Features
★Significant energy-saving effect: The three-dimensional triangular wound core is seamless, without high energy consumption areas, giving full play to the high magnetic conductivity characteristics of high-quality core materials, greatly reducing losses caused by air gaps at the joints.
★Miniaturization: High space utilization coefficient. The transformer adopts a triangular structure, so the volume is smaller than conventional transformers, with a compact structure, beautiful appearance, and small footprint.
★Low noise: Because the three-dimensional triangular wound core is made by winding several trapezoidal materials in sequence, the silicon steel strips are tightly wound together, and the magnetic conduction direction is completely consistent with the magnetic circuit direction of the core. During operation, the vibration is small, which can solve the noise caused by the inconsistency of the magnetic circuit in the stacked core, and the noise can be reduced to the minimum.
