TEWC Business Summary

Ta Tun Electric Wire & Cable Co., Ltd. (TEWC) operates a vertically integrated business model centered on the manufacturing, processing, and installation of specialized power cables and electrical equipment. Revenue is primarily generated through high-margin infrastructure contracts, including the production of extra-high-voltage (EHV) cables up to 345kV, rubber-insulated power cables, and comprehensive engineering services for power transmission and distribution lines. The company’s primary business segments are categorized by voltage capacity—spanning EHV, medium-to-high, and low-voltage solutions—alongside a dominant niche in 600V Hypalon rubber cables for industrial applications. TEWC currently holds a leading market position as the top supplier for Taiwan Power Company’s (Taipower) grid resilience programs and serves critical high-tech clients such as TSMC. Its primary domestic competitors include Ta Ya Electric Wire & Cable (1609.TW), Hua Eng Wire & Cable (1608.TW), and Hong Tai Electric Industrial (1612.TW), against whom TEWC differentiates itself through its specialized EHV manufacturing capacity and one-stop installation services. The leadership team is anchored by Chairman Lin Jhih-Ming, who also assumed the role of Chief Strategy Officer (CSO) in March 2026 to oversee the company’s post-IPO expansion and technological roadmap. President and CEO Yang Bo-Wun, appointed in 2025, brings extensive operational expertise from his previous tenure as Vice President of the Business Department and holds an MBA from National Central University. The executive board is further strengthened by Vice Chairman Li Ya-Ling, who concurrently leads Guan Shan Lin Construction, and CFO Su Yun-Ruei. Founded in 1962 and headquartered in Taoyuan, TEWC has transitioned from a family-founded enterprise to a publicly traded industry leader on the TWSE as of January 2026, supported by a board focused on energy transition and semiconductor-grade power infrastructure.
