SH-V type reduced high-pressure bus duct

A compact high-voltage bus duct that supports high dielectric strength and electrical safety due to the insulation of the conductor.

Due to the insulation of the conductor, the occupied area has been reduced compared to conventional high-voltage bus ducts, allowing for a comfortable connection to distribution boards with a width of 600mm to 700mm. Additionally, in order to allow for cleaning of all insulators, the duct has a structure that can be opened along its entire length on both the top and bottom, making it a safe design that can accommodate insulation degradation in harsh environments. For more details, please contact us through the inquiry form.

New factory "Ayase Plant" begins production.

Manufacturing capacity is approximately 1.5 times greater! By having multiple manufacturing bases, we achieve BCP (Business Continuity Plan) response and stable supply.

Kyoudo Kaitech Co., Ltd. began construction of the new factory "Ayase Plant" on July 1, 2019, and started production on July 1, 2020. The construction of the "Ayase Plant" aims to address BCP (Business Continuity Planning) and the increasing demand for bus ducts. We will enhance productivity by establishing a continuous manufacturing line that only allows horizontal movement, which was impossible at the current Kanagawa Technical Center, and by semi-automating the sheet metal processing that is currently done manually. Our company offers a wide range of bus duct products, including the "E-BD type insulated bus duct" and the "F-PE type fire-resistant bus duct." We also handle the SS-T type low-pressure trunk line system "Shaft Star," which has been developed specifically for medium-sized buildings such as tenant buildings and apartments, as well as logistics warehouses. *For more details, please refer to the PDF document or feel free to contact us.
