Intelligient control, integrated with enclosure, compact structure and high environmentaladaptability for outdoor applications. 2. The three-limb iron core is made of oblique cut Grain-oriented, seven-step silicon steellaminations insulated on both sides, guaranteeing low losses and low noise. These values are evenimproved by laser treatment. It is protected on the surface with a flash-proof varnish in orderto prevent the sheet from corrosion and to reduce the noise. 3. Clamping frame: it is processed by CNC cutting, bending and then one-time punch forming, thehole's size is accurate and the appearance looks delicate. 4. The winding coil is made of oxygen-free copper, class H for main insulation materials and coilis insulated by NOMEX paper of DUPONT brand, LV winding is isolated by copper foils. All thesemake the heat-resistant is up to 220ºC, with excellent overload capacity and low loss, but highefficiency. 5. Hengfengyou practices strictly exclusive casting system of F(155ºC) or H(180ºC), and the epoxyresin is injected and casted in the vacuum machine, so it's highly insulated, dust-proof andmoisture-proof, which ensures stable and reliable performance.Our workshopofCompact TransformerCompany IntroductionDistribution Board BoxQingdao Hengfengyou Electrical Engineering Co., Ltd.
