About the Brand
We provide high- and low-voltage power equipment and turnkey distribution solutions, including transformers, prefabricated substations, and switchgear. As the manufacturer, XIAOPAI designs and builds this equipment in-house and provides direct-from-production customization, system integration and global export services.

Located in Wenzhou, Zhejiang, Wenzhou Xiaopai Electric Power Technology Co., Ltd. (XIAOPAI) operates two business modules. Power transmission equipment — transformers, vacuum circuit breakers, switchgear cabinets and prefabricated substations — is designed, manufactured and integrated by XIAOPAI. Flexible packaging machinery is supplied by XIAOPAI as a complete line through two supply routes: solventless laminating machines come from SINSTAR, whose authorized global distributor XIAOPAI is, and blown film, flexo printing, slitting and paper tube cutting lines come from other long-established Chinese manufacturers that XIAOPAI works with. Across both modules XIAOPAI acts as the single contracting party, handling equipment integration, export documentation, sales and technical services for customers worldwide.

In power transmission equipment, XIAOPAI manufactures transformers (dry-type, oil-immersed and prefabricated substations), HV/LV circuit breakers and complete switchgear cabinets, covering HV/LV power transmission & distribution, industrial power, municipal engineering and new energy applications — engineered for stability, safety and durability.

As the authorized global distributor of SINSTAR, we supply solventless laminating machines directly from SINSTAR's factory, backed by proven technology, reliable delivery, and comprehensive after-sales support.

Why Choose Our Solvent-Free Laminator
When selecting a laminating machine, customers often find themselves torn between solvent-free and solvent-based models for various reasons. Why has this changed for us? Because Sinstar is the market leader in China’s solvent-free laminating machine sector. Founded in 2005, Sinstar specializes in the R&D and production of laminating machines. To date, our products have been sold to 38 countries, with total sales exceeding 2,680 units, and we have been recognized as a National High-Tech Enterprise. We have also obtained CE certification and ISO 9001 certification.
One-stop flexible packaging solution: blown film, solventless laminating, flexo printing, slitting and paper tube cutting mac
Film Blowing — Turn plastic granules into high-quality blown film, the foundation of every flexible package.
Solventless Lamination — Eco-friendly, high-speed bonding with SINSTAR-certified laminators (e.g. WRCFP 1050DA). Lower VOC, full compliance, superior bond strength.
Printing & Slitting — Precision converting from printed composite film to ready-to-use rolls.
Other Equipment & Auxiliaries — Supporting machines that complete your line — paper tube cutting and more — so your plant stays self-sufficient from core to edge.
From resin to roll, in one coordinated line: Raw Material → Film Blowing → Solventless Lamination → Printing → Slitting → Other Equipment (paper tube cutting & auxiliaries) → Finished Rolls

Power transmission equipment, 6 kV to 35 kV

XIAOPAI designs and manufactures power transmission equipment in Wenzhou, Zhejiang, China: sealed oil-immersed transformers, dry-type epoxy-resin cast transformers, vacuum circuit breakers and high-voltage and low-voltage switchgear cabinets for systems from 6 kV to 35 kV.

Sealed oil-immersed power transformers, S9 to S22

The S9 to S22 sealed-tank range covers 6-10 kV and 35 kV for outdoor substations, industrial yards and grid-side distribution. A sealed tank removes the need for a conservator, which cuts maintenance work and oil-leak risk. Against dry-type units of the same rating, oil-immersed units run 20 to 30 percent lower in unit cost with higher overload tolerance.

Dry-type epoxy-resin cast transformers, SC(B)9 to SC(B)13

Built for indoor installation where fire safety, low noise and zero oil leakage matter: buildings, hospitals, shopping malls, data centres, underground substations and metro stations. Cast-resin windings with vacuum-pressure impregnation give high short-circuit strength and low partial discharge.

Vacuum circuit breakers, 12 kV to 40.5 kV

Models include VSG-12 indoor withdrawable, ZW32-12 and ZW32-24 outdoor pole-mounted, ZN85-40.5 indoor, and the FZRN12/25-12D load switch-fuse combination. All are rated for 10,000 mechanical operations and comply with IEC 62271-100.

High-voltage and low-voltage switchgear cabinets

Cabinets integrating breakers, disconnectors, current and voltage transformers, protection relays and metering, assembled and tested in factory as a complete switchgear assembly to IEC 61439.

Flexible packaging equipment and materials

For flexible packaging, XIAOPAI is the authorized global distributor of SINSTAR solventless laminating machines, and supplies blown film extrusion, CI flexo printing, slitting and rewinding, hot-knife laminating and paper tube cutting lines, plus raw materials and finished film. SINSTAR designs and manufactures the solventless laminators in Chongqing, China; XIAOPAI handles market promotion, export documentation, single-point accountability and after-sales coordination.

Solventless laminating machines, SINSTAR Suplock series

WRJ Fi9 and WRJ S1 digital models run at 450 to 500 m/min with zero solvent residue and roughly 50,000 to 60,000 kWh per year lower energy use than solvent-based laminators. Substrates include PET, BOPP, CPP, PE, aluminium foil and paper.

Three-layer blown film extrusion

The ABC65/75/65-1800 line uses IBC internal bubble cooling at 100 to 120 m/min, 200 to 300 kg/h output and 1,800 mm fold diameter, running LDPE, LLDPE, MLLDPE and HDPE.

Printing, laminating, slitting and paper tube cutting

CI flexo Master Series presses run 4 to 8 colours at 800 mm maximum feeding width and 150 m/min. The XPM-1080RN hot-knife laminator handles sheets up to 1,080 by 1,500 mm at 105 m/min for film above 127 gsm. The CLFQ-W1100 rewinding and slitting machine runs at 400 m/min with 0.30 mm EPC correction accuracy. The Q5-1200 paper tube re-cutter cuts one tube in 0.5 s with 0.01 mm positioning resolution.

How an order works

Power transmission equipment is engineered and manufactured in-house by XIAOPAI. Solventless laminating machines are designed and manufactured by SINSTAR and supplied by XIAOPAI as its authorized global distributor. In both cases the buyer deals with one accountable point of contact: XIAOPAI quotes, coordinates production, prepares export packaging and customs documentation, and handles after-sales coordination. Shipment is normally FOB Ningbo or Shanghai.

What ships with every unit

CE-marked equipment, ISO 9001 company certification, routine test reports issued per unit, seaworthy crating with moisture barrier, full customs documentation, and an English operation and maintenance manual.

Certifications and standards

Transformers are routine-tested to IEC 60076 covering temperature rise, impulse voltage and short-circuit withstand. Circuit breakers comply with IEC 62271-100. Switchgear assemblies comply with IEC 61439. Packaging machinery is CE certified with full factory test documentation. Company quality system: ISO 9001.
