Ang serye ng kontaktor na may vacuum sa medium voltage ay may integrated na insuladong frame structure, na pinagsamaan ng high-quality na vacuum interrupters. Ito ay nagbibigay ng simple at maasahang secondary control, stable na performance, at magandang panglabas na buong insuladong cover. Ang aming kompanya ay nagsagawa ng pag-optimize sa transmission mechanism, na nagresulta sa compact na structure, mabuting synchronization performance, at minimal na bounce. May tatlong modelo ang available: electromagnetic holding type, mechanical holding type, at permanent magnet holding type, na nagbibigay-daan sa mga user na pumili ng appropriate na operating mechanism batay sa iba't ibang aplikasyon. Ang aming mechanical holding mechanism ay isang patented na produkto, na nagbibigay ng stable at maasahang operasyon, walang mechanical wear, mahaba ang service life, mababang switching current, at walang power wastage, kaya ito ay isang energy-efficient na produkto.
