JECA Fair 2026 74th Electrical Construction Industry Exhibition Will be held at Tokyo Big Sight from May 27 (Wednesday) to May 29 (Friday), 2025. The "Waterproof Sleeve for Underground Exterior Walls - Pipe-in-Sleeve," which was submitted by Furukawa Electric Co., Ltd., has been awarded the "Encouragement Award from the Japan Electrical Construction Association." "Innovation in Underground Beam Sleeve Construction!" We deliver a PVC sleeve with a pre-treated "waterproofing" process applied in the factory, integrated with electrical conduits (E-Flex) in a prefabricated state. At the construction site, there is no need for troublesome "waterproofing," and after installation, only joint connections are required, improving work efficiency and achieving "labor-saving." Furthermore, it provides stable waterproof performance for flood prevention and water resistance construction! It enhances the waterproof performance of buildings, balancing work efficiency and construction quality! This is all thanks to the support of developers, design firms, general contractors, subcontractors, and trading companies. We will continue to strive towards the next stage. We sincerely appreciate your continued support.

The "JECA Fair 2026 74th Electrical Industry Exhibition" will be held soon from May 27 (Wednesday) to May 29 (Friday) at Tokyo Big Sight. We are planning to showcase at the booth of Furukawa Electric Co., Ltd. "Waterproof Sleeve for Underground Outer Walls - Pipe in Sleeve" We have compiled the inquiries we received regarding the product launch and have created an FAQ, which we have started to publish. Since last year's JECA Fair, we have received numerous inquiries and requests from various fields, for which we are truly grateful. We kindly ask you to take a look. Thank you.

As always, our well-known "Non-drying Polyolefin-based One-component Water Stop Putty TometaroⓇ" and the "Underground Wall Waterproof Sleeve Pipe-in-Sleeve (abbreviated as PIS)," which has been well-received since its launch last year, will be exhibited at the "JECA FAIR 2026 - 74th Electrical Equipment Industry Exhibition" held at Tokyo Big Sight. This exhibition is the largest comprehensive electrical equipment exhibition in Japan, showcasing new products related to electrical equipment, tools, measuring instruments, software, systems, and more, as well as introducing construction techniques, improving construction efficiency, academic presentations, and initiatives for reforming work styles in the electrical equipment industry. The exhibition will be at the booth of Furukawa Electric Co., Ltd. We sincerely look forward to your visit.

[Proposal for Polyethylene Access Holes] We believe everyone is facing difficulties... “To contractors planning to use rigid PVC pipes with a diameter of 600mm” Due to the impact of the Middle East conflict on the supply of domestic PVC products, we hope that our polyethylene access holes, EP-Sleeve, can be of some assistance... * We have stock available only for the 600mm size within Tokyo. * Of course, we also offer cutting services.

A new innovative product for the underground beam sleeve construction is about to be released! Introducing the upgraded version of the "Pipe-in-Sleeve" that you have come to love! "Pipe-in-Sleeve T-type," abbreviated as PIS-T. The T-type features a "water drainage PVC flange" welded with the same material (PVC) to the outer layer of the conventional PIS PVC sleeve. This method serves as an alternative to the ring-shaped or band-shaped water-stopping material on the outer circumference of the PVC sleeve, responding to the strong requests from construction companies. Achieving both work efficiency and construction quality! Stay tuned for the official launch!

Proposals for flood prevention and waterproofing construction in general, starting with the familiar water-stopping putty Tome Taro! From cable penetration points to waterproof sleeves for underground exterior walls, and all the way to completely waterproof and odor-proof manhole covers, we solve the "water issues" of underground facilities all at once! ■ [NETIS] Non-drying polyolefin-based one-component water-stopping putty Tome Taro® ■ Waterproof sleeve for underground exterior walls - Pipe-in-sleeve ■ Water pressure-resistant waterproof manhole cover (manhole lid) and machine hatch *For detailed information on each product, please refer to the individual catalogs.

Polyethylene Human Passage (Human Passage Opening) EP-Sleeve ■ High Pressure Resistance: Due to its smooth double structure with a corrugated inner surface, it is strong against impacts and external pressure, possessing excellent flat strength. ■ Lightweight Material: Compared to rigid PVC pipes, it is lightweight. It enhances transportation and work efficiency, contributing to "labor-saving" at construction sites. ■ Rust Resistant: Made of high-density polyethylene, it is safe and secure for installation in water areas! ■ Cold and Chemical Resistant: Compared to rigid PVC pipes, it is suitable for installation in extremely cold regions and shows no deterioration against most chemicals. The polyethylene sleeve "accelerates the 'efficiency' of the site with its 'lightweight'!" A material that combines high pressure strength with "lightweight," which leads to direct construction usability. In particular, while rigid PVC pipes weigh about 53 kg/m, the polyethylene sleeve weighs about 17 kg/m, showcasing an overwhelming weight difference! We guarantee a definite improvement in work efficiency at construction sites. Furthermore, it also contributes to reducing the burden on workers and lowering accident risks, enhancing safety!

"Lightweight" accelerates "efficiency" on site! Materials that combine high pressure resistance and direct workability with "lightweight." In particular, rigid polyvinyl chloride pipes (PVC) weigh about 53 kg/m, while polyethylene sleeves weigh only about 17 kg/m, showing a significant weight difference! We guarantee a definite improvement in work efficiency at construction sites. Furthermore, it also contributes to reducing the burden on workers and lowering the risk of accidents, enhancing safety!

Pikaristar is a release agent developed to safely remove Tometaro, a non-drying polyolefin-based one-component water stop agent (non-curing water stop material) made entirely from "natural materials" that is safe for the environment and human health. When re-entering cables into a conduit where Tometaro has been applied, this spray-type liquid allows for the safe and quick removal/release of Tometaro. This product not only facilitates the removal of Tometaro but also enables the peeling and removal of dirt that inevitably occurs during cable connection work, as well as "stubborn residues" that have dissolved over time! Furthermore, it can be utilized not only for the aforementioned "industrial applications" but also for various "household applications." 【Features】 ■ An all-purpose release agent for "various applications" ■ Made from "natural materials," considerate of the environment and people

JECA Fair 2025, 73rd Electrical Construction Industry Exhibition May 28 (Wed) - May 30 (Fri), 2025 At the booth of Furukawa Electric Co., Ltd. in Intex Osaka, we announced: "Waterproof Sleeve for Underground Exterior Walls (Underground Beam Sleeve) - Pipe in Sleeve" Innovating Underground Beam Sleeve Construction! We apply "waterproof treatment" in advance at the factory to the outer space (gap) between the PVC sleeve and the electrical conduit (E-Flex), delivering it in a prefabricated (integrated) state. At the construction site, there is no need for cumbersome "waterproof treatment," and after installation, only joint connections are required, improving work efficiency and reducing labor. Furthermore, it ensures stable waterproof performance for flood prevention and waterproofing work! Enhancing the waterproof performance of buildings while balancing work efficiency and construction quality! We sincerely appreciate the inquiries we have received from various fields since the launch. Currently, we are experiencing a high volume of inquiries, and for large orders, we kindly ask for orders to be placed with ample lead time beyond the usual delivery schedule.
