2results about How to "Good capacitance characteristics" patented technology

The present disclosure provides a multilayer ceramic capacitor and a method for manufacturing the same. The multilayer ceramic capacitor includes: a capacitor body including a dielectric layer and an inner electrode; and an external electrode on an outer side of the capacitor body, in which the dielectric layer includes glass having a second phase including Ga and Li.

This invention discloses a fiber-impregnated capacitive bushing, comprising an insulating substrate layer, a dielectric reinforcement layer, a liquid filling layer, a mechanical reinforcement layer, and an outer protective structure. The insulating substrate layer is made of impregnated glass fiber, aramid fiber, or polyimide fiber, forming a tubular structure. The dielectric reinforcement layer is located outside the insulating substrate layer and is filled with a porous, sintered high-dielectric-content material. This invention effectively improves capacitance characteristics and reduces the risk of partial discharge (PD) by combining a porous dielectric reinforcement layer with a high dielectric constant and a liquid filling layer. It also enhances heat dissipation through heat-conducting channels and a thermally conductive filling layer, avoiding excessive local temperature rise. Simultaneously, a cross-wound mechanical reinforcement layer improves the structural strength of the bushing and enhances its long-term operational stability. This bushing is suitable for high-voltage transmission equipment, capacitors, cable insulation systems, and other fields, improving the electrical insulation performance and reliability of the equipment.
