SCB series dry‑type transformer adopts epoxy vacuum casting process. Based on fully absorbing the technologies of similar domestic and foreign products, it is manufactured by using high‑quality raw materials, advanced production equipment, scientific manufacturing processes and strict testing measures, and acts as an upgraded substitute for oil‑immersed transformers.

The on‑load tap‑changing dry‑type transformer is a complete set of combined electrical equipment fitted with a vacuum on‑load tap‑changer. Equipped with an automatically‑controlled motor‑driven mechanism, the on‑load tap‑changer enables on‑load voltage regulation. A program‑control interface can be provided upon user requirements to facilitate on‑site or remote control.

With a voltage class of 35 kV and transformer capacity ranging from 30 kVA to 20 000 kVA, this 35 kV‑class insulated dry‑type transformer is developed by our company based on digesting and absorbing imported technologies. Its design and manufacture comply with IEC 60076, GB 1094, GB/T 10228 and other relevant standards. The transformer directly steps down 35 kV grid power to 400 V distribution power or 10 kV transmission power for end‑users. Owing to its outstanding advantages, it has been widely adopted in a growing number of engineering projects.

The SCBH‑series amorphous alloy dry‑type transformer is manufactured with an amorphous alloy core. It not only delivers the excellent properties of conventional dry‑type transformers including flame retardancy, self‑extinguishing capability, moisture resistance and crack resistance, but also features low no‑load loss and low no‑load current.

SGB‑series products adopt DuPont (USA) technology as open‑type dry‑type transformers, designated as SG type with H‑class thermal insulation rating. Insulation is realized by DuPont NOMEX paper, which features good anti‑aging, shrink‑resistance and compression‑resistance performance, ensuring compact coil structure even after years of transformer operation. With segmented‑layer winding structure, the coils are manufactured through VPI vacuum‑pressure cyclic impregnation process using H‑class solvent‑free insulating varnish and subsequent high‑temperature curing. It possesses excellent electrical, heat‑dissipation, mechanical and insulating properties, and is one of domestic distribution transformers with relatively high insulation class.

The epoxy‑cast dry‑type earthing transformer is core equipment for 6‑35 kV neutral‑point‑ungrounded power grids. It adopts epoxy resin vacuum casting forming technology with high winding integrity, and provides an artificial neutral point via ZN and other vector group connections. It can be fitted with secondary windings for auxiliary power supply, limit earth‑fault current and suppress overvoltage to guarantee grid stability, covering mainstream capacity specifications of 2500 kVA and below.

A split‑winding transformer is a multi‑winding power transformer in which each phase comprises one high‑voltage winding and two or more low‑voltage windings of identical voltage and capacity.

It is mainly supporting complete cabinets of medium‑ and high‑voltage frequency converters and variable‑frequency speed regulators. When combined with frequency‑conversion power units, it can effectively counteract harmonics, improve power grid quality, regulate motor speed efficiently and enhance power‑generation quality.

Specially designed for supporting high‑voltage frequency converters, it adopts Class‑H insulating materials. Multi‑winding phase‑shifting technology is applied to realize multi‑pulse rectification, which can effectively suppress harmonics and provide stable isolated power supply for frequency‑conversion systems.
