BMC is a core high-performance thermosetting substrate in the field of high-voltage insulation. Leveraging industry-leading electrical insulation properties and adaptability to operatin conditions, it has become one of the mainstream material choices for insulating structural components in high-voltage electrical equipment. With a volume resistivity exceedin10¹² Ω·cm, a breakdown strength reaching over 15 kV/mm, and arc resistance exceeding 180 seconds, it meets the UL94 V0 flammability standard. tains stable insulation performance even under harsh conditions such as high temperatures, humidity, and contamination, effectively avoiding safety hazards like tracking and breakdown. Widely applied in scenarios including insulating pas for high-voltage switchgear, transformer housing, post insulators, core components of surge arresters, and arc extinguishing chambers of high-voltage circuit breakers, it provides safe e insulation solutions for high-voltage transmission and distribution, new energy high-voltage systems, and other fields.
