Product Selection Manual - V2
XIAOPAI supplies two distinct equipment lines for global B2B customers, and this manual is the single entry point for choosing between them. On the power side we design, manufacture and integrate power transmission equipment — power transformers from distribution class up to 230 kV / 200 MVA, medium- and high-voltage vacuum circuit breakers, switchgear, and packaged substations. On the flexible packaging side we are the authorized global distributor of SINSTAR solventless laminating machines and related converting lines, and we provide one-stop solution service around that equipment. Both lines are sold to the same kind of customer — engineering buyers, EPC contractors, brand owners and traders who need CE- or ISO-grade equipment, predictable lead times, and a single point of accountability for export logistics.
## What this manual covers
The manual is split into two independent selection paths so you only read what is relevant. Buyers looking for substations, factories, renewable step-up or utility feeders should follow the power transmission section, which walks through transformer rating, vacuum circuit breaker selection, switchgear choice and packaged substation sizing. Buyers looking for food, beverage, personal care or industrial flexible packaging lines should follow the packaging section, which walks through laminator selection, film structure, blown film line selection and converting (printing, slitting) choices. If your project touches both, read both — the two paths are independent and the procurement paperwork is separate.
## How to choose power transmission equipment
For transformers, the four parameters that drive 80 percent of the decision are rated power (kVA or MVA), voltage ratio (HV / LV), cooling type (ONAN, ONAF, OFAF, or dry-type AN / AF), and installation environment (indoor, outdoor, altitude, ambient). Once those are fixed the rest — impedance, tap range, vector group, losses — follows from the applicable standard, which in our export markets is usually IEC 60076, with GB 1094 for China and IEEE C57.12.00 for North American documentation. For vacuum circuit breakers, the key parameters are rated voltage (most projects are 12 kV, 24 kV or 40.5 kV), rated current, short-circuit breaking capacity, and whether you need withdrawable or fixed mounting. Indoor metal-clad switchgear is the default for factory and substation use; outdoor pole-mounted or ring main units are used for distribution feeders.
For substations, the choice is usually between a pad-mounted compact substation (for residential, commercial and light industrial loads up to about 40.5 kV) and a containerised or prefabricated substation for utility or large industrial sites. Each has implications for footprint, transport, civil work and commissioning time, and we list the typical sizing logic in the relevant selection guide. The catalogue PDF at the bottom of this page contains the full parameter matrix, but the short version is: if you can describe your load, your grid voltage and your site constraints, we can size a complete power package in one quotation.
## How to choose flexible packaging equipment
For solventless laminating machines the selection is driven by web width, machine speed, substrate combination and the number of adhesive stations. A 1300 mm machine running 250 m/min is the standard workhorse for most food and personal care film structures, while narrower or wider machines are used for specialty applications. SINSTAR machines cover digital control, twin-component adhesive systems and full servo tension control. For blown film, the choice is between mono-layer lines (for simple products like plain PE bags) and multi-layer co-extrusion lines (for barrier film with EVOH or nylon). For converting downstream, CI flexo printing machines and slitting-rewinding machines are sized by web width, print repeat and number of colours.
The packaging section assumes you already know your end product and the substrate structure. If you are still scoping a new flexible packaging line, start with our one-stop solution overview and our solventless laminator buyer guide — both linked at the bottom of this page — and we will work back from your product specification to the machine specification rather than the other way around.
## How to use this manual
Each section is written so you can read it in fifteen minutes and come out with a shortlist of two or three product families. The tables are sized for buyer use, not for engineering certification — the certification matrix and full type-test reports are bundled with every quotation. If you are under time pressure, send us your load list, grid voltage and site photos for the power side, or your product spec, expected output and substrate samples for the packaging side, and we will return a sized proposal within two working days.

## Frequently asked questions
**Q: Can I order only the power side or only the packaging side?**
A: Yes. The two lines are sold and serviced independently. Power quotations go through our transformer / VCB engineering team in Wenzhou; packaging quotations go through our SINSTAR partnership team. You can place one order, two orders, or run both in parallel — your account manager will coordinate on the export side.
**Q: What standards do your power transformers comply with?**
A: Routine and type tests are performed to IEC 60076 (parts 1, 2, 3 and 11 depending on the unit), GB 1094 for the China market, and IEEE C57.12.00 when the end user requires North American documentation. Test reports are supplied with each unit.
**Q: Do you supply installation and commissioning?**
A: For power equipment we can dispatch supervisors for on-site commissioning on a per-project basis; for packaging lines SINSTAR provides installation, commissioning and operator training, usually included in the equipment price for export orders. Let us know at quotation stage and we will build the right scope.
