I. Product Overview

This high-voltage coil frame is made of high-temperature-resistant and flame-retardant BMC molding material, specifically designed for various step-up high-voltage coils and pulse ignition transformers; the outer surface of the cylinder is equipped with multi-layer uniform annular grooves, which can orderly wrap the enameled copper wire in layers, the groove partition structure can effectively isolate high and low voltage windings, significantly improve the interlayer insulation and voltage resistance performance, and avoid coil breakdown and short-circuit under high-voltage conditions.

The hollow cavity in the frame can accurately fit the silicon steel core, with internal reinforcing ribs ensuring assembly fit without movement; the top stopper slot is used for positioning the upper and lower shells, while the side walls have pre-buried metal conductive pins. The ends of the coil can be wrapped and fixed on the pins to achieve stable power extraction. The BMC material combines excellent temperature resistance, high-voltage insulation, and mechanical rigidity, will not soften or deform, nor leak electricity or puncture under long-term electrically heated environments, and has excellent moisture resistance and arc resistance, suitable for stringent working conditions of various high and low-voltage electromagnetic equipment.

Tubular size, wire slot quantity and spacing, and pin arrangement can be adjusted as required; the sample structure is replicated with a 1:1 mold. Each product is inspected for insulation withstand voltage andOverall dimensions before shipment, and only when all electrical specifications meet the standards can mass delivery take place.

Part Two: Core Highlights of Craftsmanship

1. BMC integral molding with one-piece die forming, overall insulation without splicing gaps
   The whole cylinder, wire channel, and positioning slots are formed in one high-pressure molding process, with no gaps or delamination, eliminating thehidden danger of high-voltage arc piercing, and far superior insulation performance compared to ordinary nylon injection-molded parts.
2. Segmented annular lineGroove design, neat winding arrangement with higher pressure resistance
   Each layer of coil is separated by an independent groove, with copper wire neatly wrapped without crossing or stacking, effectively reducing inter-turn capacitance and enhancing the transformer's working stability and voltage withstand limit.
3. Pre-embedded metal pins integrated embedding, leads are firm and not easy to fall off
   The terminal housing is firmly embedded in the side wall during injection molding, ensuring that pulling the wire will not cause the terminal to loosen or dislodge, providing a stable and reliable electrical connection.
4. High-temperature and arc-resistant material, durable in wide temperature environments
   Can withstand working temperatures above 150℃ for long periods, is not easily carbonized and cracked under instantaneous high temperatures and arc impacts, and is suitable for continuous heating conditions of high-voltage coils.
