WOER's product ecosystem is organized around six series — electronic (single-wall, dual-wall, identification heat-shrink tubes; busbar products), power (heat-shrink and cold-shrink cable accessories for 0.6/1kV to 35kV applications), separable cable accessories (European and American-style connectors), cables and new energy (including EV charging guns and stations), foam materials (radiation cross-linked polyethylene and polypropylene foams), and PLA 3D printing filament. Its technology platform centers on electron-beam irradiation of polyolefin and silicone materials to produce proprietary polymer formulations, yielding over 2,500 SKUs and a patent portfolio of 216+ cumulative applications with 118 authorized patents (as of end-2012). Distinctive proprietary offerings include halogen-free nuclear-grade 1E Class K1 cable accessories (qualified for the Hualong One reactor K-2/K-3 project in Pakistan), ceramic silicone rubber fire-resistant material with 11 related patents, full cold-shrink technology with triple-layer waterproof sealing using imported liquid silicone rubber, and magnetic heat-shrink tubing for EMC improvement.

The business model is sales-led and hardware-driven. The primary GTM is a direct enterprise sales force of 400+ personnel organized into 40+ sales branches with local warehouse inventory across major Chinese cities, complemented by international sales divisions covering more than 60 countries across Asia, Europe, and the Americas with localized multilingual websites. The customer base spans China's state-owned power grid operators (State Grid, China Southern Power Grid), energy majors (Sinopec, CNPC), telecom/electronics (Huawei as a top-10 customer after the 2012 LTK acquisition), nuclear power (Pakistan Hualong One project), rail transit, EV charging (Shenzhen Bus Group, Luobinsen, Hangzhou Power Supply Company), and commercial real estate (Shenzhen Metro, Shenzhen Binhai Hospital). Consumer-facing products such as the Fushe (富社) radiation cross-linked halogen-free flame-retardant wire are sold through Tmall, JD.com, and Alibaba 1688 flagship stores at a 10-20% premium over PVC alternatives.
