Product advantages
Intelligent capacitors utilize metallized polypropylene film as the dielectric and exhibit the self-healing phenomenon, having high dielectric strength, low dielectric losses, good heat resistance, and environmental protection. These properties help the capacitor return to normal operation soon after a local fault in high voltages and high-temperature operating conditions with less power loss and meeting environmental demands, hence greatly extending its life and improving energy efficiency.
Terminal blocks facilitate convenient and fast cable connections by designing specific features that lessen the chances of bad contact and increase safety in the system. The terminal blocks are also easy to de-assemble and replace, thus reducing maintenance time and able to accommodate various cable specifications, thus opening flexible options for connection to meet a variety of applications. These benefits have placed terminal blocks in a critical position with regard to smart capacitors and other electrical equipment.
Molded case circuit breakers are lightweight and corrosion-resistant and possess excellent insulation properties, ensuring stable operation in moist or corrosive environments to protect the equipment. In addition, the plastic case is flexible in design and can be customized in different shapes and sizes according to requirements. Further, it is cheaper compared to metal cases, which cuts down the manufacturing and maintenance costs of the overall equipment. All these merits have allowed the present trend of utilizing molded case circuit breakers in modern power systems.
