Launched the industry's first adjustable spacer developed for "SFVP" power cable protection tubes.

  • PRODUCT

Kokugawa Electric Co., Ltd. will launch the industry's first adjustable spacer, which allows for three different settings of separation distance, developed for the "SFVP" power cable protection tube suitable for underground transmission of renewable energy, starting from May 30, 2025. This adjustable spacer can set the separation distance from 250mm to 350mm in three stages, allowing for adjustments to avoid unexpected obstacles during construction. Additionally, by ensuring an appropriate separation distance between the protection tubes, it can prevent issues such as cable outages and reduced transmission efficiency due to cable overheating.

Announcement of the release of the electric cable protection tube "SFVP"

  • PRODUCT

Kokugaw Electric Industry Co., Ltd. has released a power cable protection tube 'SFVP' designed for special high-voltage cables. It excels in wire-pulling performance and ease of installation, achieving high strength through its PVC material and structure. Additionally, it is lightweight, easy to handle, and facilitates efficient installation work. With an increased inner diameter (nominal diameter +10mm), it contributes to size reduction and cost reduction during tube selection, as well as shortening construction periods and reducing construction costs. This product has been meticulously developed by cable manufacturers. We hope it will be useful in promoting the adoption of renewable energy.
