WOPENG Fully Insulated Tubular Bus Bar serves as the core solution for the new generation of power transmission systems. It adopts a fully shielded, fully insulated, and fully protected design to eliminate risks of electric shock and external interference. The product covers a full voltage range from 0.4kV to 550kV, with a wide temperature adaptation capability from -45℃ to 250℃, seismic resistance up to an intensity of 8 degrees, and pollution resistance meeting the stringent requirements of Class V environments. Through a multi-layer insulation structure and capacitive voltage equalization technology, it achieves uniform electric field distribution, with partial discharge levels below 5pC and a design lifespan exceeding 30 years.

Medium and low voltage bus bars primarily include the full series of insulated tubular bus bars rated at 0.4 kV, 10 kV, and 35 kV. Among them, the 0.4 kV low‑voltage series covers rated currents from 1000 A to 8000 A, employs copper tubular conductors and epoxy casting technology, and maintains a temperature rise below 30 K. The 10 kV medium‑voltage series and 35 kV high‑voltage series both cover a current range of 1000 A–8000 A, utilizing epoxy casting and wrapped insulation processes respectively, with temperature‑rise limits of <30 K and <45 K respectively. All medium and low voltage bus bars comply with DL/T 1658‑2016 and DL/T 5789‑2019 standards. They feature a fully insulated enclosed structure, capacitive screen voltage‑grading technology, and high‑purity T2 copper conductors. These products offer comprehensive advantages such as high current‑carrying capacity, low skin effect, high mechanical strength, long span capability, vibration resistance, full insulation shielding, high protection rating, and adaptability to harsh environments. They are widely used in scenarios including substations, wind‑solar booster stations, industrial power distribution, and data centers.
