Insulation materials, engineered since 2008
Hengsheng Technology supplies insulation materials for transformers, motors, reactors and electrical equipment — and the production equipment behind insulation manufacturing.
Who we are
Hengsheng Technology Co., Ltd. was founded in 2008. We supply insulation materials for transformers, motors, reactors and electrical equipment: insulating paper, flexible laminates, rigid boards and films, impregnating varnishes, sleevings, binding tapes and machined parts.
We treat insulation as part of the winding, insertion, impregnation and assembly process — not as a standalone material. Our focus is therefore material performance + process fit + batch consistency.
From incoming paper, film, glass cloth, aramid paper and resin to slitting, laminating, die-cutting, machining, impregnation and packing, we control thickness, density, adhesive and resin content, breakdown voltage and tensile strength against the relevant product standard.
A second business line supplies the production equipment used to manufacture these materials. Equipment models and specifications are being documented and we will publish them here once confirmed.

What happens on the shop floor
The catalog covers 27 materials on data pages. Behind them is a process chain that starts with raw paper, film, glass cloth, aramid paper and resin.

- Packing
- Delivery
Customization is more than a width change
Temperature class, construction, adhesive or resin content, roll size, packaging and machining all affect winding, impregnation and assembly. Define the application first, then the specification.
Customization scope
- Thickness / width / roll — slitting, rewinding, fixed length; core ID and max OD set to your equipment.
- Construction / class — single layer, laminate, dotted, prepreg; Class A/E/B/F/H.
- Colour / flame retardancy / packing — colour, marking, length per roll, carton or pallet.
- Machined parts — cutting, drilling, milling, turning, CNC; inspected to drawing.
Selection in four steps
- Temperature class →
- Construction and thickness →
- Process and delivery form →
- Key electrical / mechanical data and validation.
Sampling to production
Requirement → drawing / sample → material selection → sampling → inspection → production → packing. Small batches and dimensional or performance checks are part of the flow, not an afterthought.
