Company scope
What the company makes
Taihu Yuanda, registered as 浙江太湖远大新材料股份有限公司, produces polymer compounds for cable insulation, sheathing and shielding. The company dates its start to 2004. Its photovoltaic product is TGWH5200, a silane-crosslinked low-smoke, halogen-free compound for the outer sheath of UL4703 PV cable. The rest of the range covers peroxide-crosslinked polyethylene, silane-crosslinked polyolefin and semiconductive compounds, which serve other cable types, high-voltage designs among them, under their own ratings.
The 2025 annual-report summary on CNINFO describes production made to order across these compound families. It adds that the grafting step for some mature low-voltage insulation products goes to outside processors. The website gives two Changxing addresses, and the report names an office at 58 Qiangye Road. When you ask for a price, find out which site makes and ships the TGWH5200 A and B components for your order.
TGWH5200 arrives with barrel and head temperatures, a screw recommendation and a choice of natural or accelerated crosslinking. That gives a cable plant enough to plan a first line trial. Approval of the finished cable then comes from your own construction, your processing settings and the lot records shipped with each delivery.

TGWH5200 PV cable sheath compound →
TGWH5200 is a silane-crosslinked low-smoke, halogen-free compound for extruding the outer sheath of UL4703 PV cable. Its grade sheet lists 11.5 MPa typical tensile strength against a 10.3 MPa minimum and a typical oxygen index of 33%. Extrusion runs at 110–130°C in… [2]
Specifications & selection questions →Where TGWH5200 fits
TGWH5200 covers the sheath of a PV cable
| Listed item | What it covers | What to request |
|---|---|---|
| TGWH5200 sheath compound | Granule feedstock for the outer layer of a PV cable. | Conductor, insulation and extrusion equipment come from other suppliers, so name them in the enquiry. |
| UL4703 / UL44 references | Standards named in the TGWH5200 product table. | The UL file or listing number that covers the compound or your finished cable. |
| VW-1 with UL insulation | Taihu Yuanda states the sheath can reach VW-1 when paired with UL insulation. | Flame results for the exact insulation and sheath pairing you plan to run. |
| High-voltage material families | Other compounds in the company range. | TGWH5200 carries no high-voltage rating on its page; ask if your design calls for one. |
Request the current grade sheet together with the qualification plan for your cable construction. [1][2]
Describe the whole cable in the enquiry
List the conductor build, insulation material, sheath dimensions and the cable standard you will certify against. Taihu Yuanda can then match the sheath grade and comment on how it pairs with your insulation layer. Mention too that the finished PV cable will be terminated with connectors and run to module junction boxes. [2]
Extrusion and cure settings from the maker
Extrusion and crosslinking settings for TGWH5200
Extruder settings
Taihu Yuanda recommends barrel zones at 110–130°C, the head at 130–135°C, and a screw designed for low-smoke, halogen-free material with a 1.2–1.5 compression ratio. Melt temperature should stay within 180°C. Use these figures to set up the first trial on your own line. [2]
Two ways to crosslink
The sheath can crosslink naturally over 3–5 days or faster in steam or water. The grade page gives no fixed accelerated cycle, so settle temperature, humidity, duration and the completion test with the maker before production. [2]
A and B packs
Component A comes in 25 kg bags and component B in 5 kg bags. The page states no mixing ratio, order of addition or open time, so get written mixing and handling instructions for each batch. [2]
Packing, storage and supply route
Packing and storage for a moisture-cured compound
Packing as shipped
TGWH5200 is vacuum packed in moisture-barrier bags of aluminium foil and polyethylene, on pallets of 1,200 kg. The maker asks that pallets are never stacked on top of each other in transit or storage. Check the delivered unit against this before you sign for it. [2]
Storage window
Keep the material clean, dry and ventilated at 0–35°C. Under those conditions the stated validity is six months. Ask for the manufacture date, when the six months begin and how long an opened bag stays usable. [2]
Who makes your lots
Taihu Yuanda produces against orders and sends some grafting of mature insulation products to outside processors, according to its annual report. The report names no outsourcing for TGWH5200. Ask which plant makes and tests your components and how you will hear about process changes. [4]
From quotation to repeat order
Four steps from compound sample to approved PV cable
Collect the grade documents
Ask for the latest TGWH5200 data sheet, written A/B mixing directions, the safety data sheet, lot certificates and the name of the producing site. Make sure each document revision matches the material on the quotation. [2]
Run a line trial
Share your extruder, screw and die details, sheath thickness and planned cure route. Log real temperatures and handling during the run, then check extrusion surface and any early crosslinking against your own plan. [2]
Test the cured cable
Agree physical, aging, cold, flame and electrical tests for your cable layers. Keep lot tests on the compound apart from tests on the finished construction, and ask for methods, conditioning and pass limits for both. [2]
Lock the baseline for repeat orders
Record grade, component lots, mixing and extrusion settings, cure conditions and accepted results. Write into the contract that changes in formulation, plant or subcontractor need your approval first. [2][4]
Project fit
Match the offering to your project
PV cable plants that need a documented sheath compound for a set cable design.
Buyers comparing silane-crosslinked halogen-free sheath materials who already have an extrusion and cure plan.
Purchasers who want mixing directions, storage rules and lot tracing written into the purchase contract.
Confirm before ordering
- The A/B mixing ratio, open-bag allowance and accelerated crosslinking cycle for your batch.
- The UL file or listing that applies, plus cable qualification and shipment test results.
- The plant that makes your grade and the company entity that signs the contract.
Facts come from the TGWH5200 grade page, Taihu Yuanda's company and contact pages, and pages 2–5 of its 2025 annual-report summary.

Does Taihu Yuanda sell PV cable-making machines?
No. It sells compound for the cable sheath. The TGWH5200 page offers no extrusion line or finished cable model. [2]
Do the 25 kg A and 5 kg B packs mean a 5:1 mix?
No. Those are bag weights. Get the actual ratio, mixing sequence and exposure limits from the maker in writing. [2]
Is TGWH5200 UL listed?
The product table names UL4703, with no file number given. Ask for the current listing documents and check that they cover your cable construction. [2]
