This shielded tube is designed to reduce noise induced into internal wiring by lightning surges and other electromagnetic disturbances.
It features a high dielectric strength, capable of withstanding an impulse voltage of 1.2/50 μs – 30 kV.
The tube can be freely cut to the desired length, allowing for easy post-installation application.

Stores 9.6 kg of CO₂ in soil, contributing to the mitigation of global warming

The amount of CO₂ stored per bag is calculated based on a carbon sequestration formula. Emissions from cement and manufacturing processes are excluded.
Based on the methodology of J-Credit for farmland application by the Ministry of Agriculture, Forestry and Fisheries.

6 kg lighter than conventional products

While the conventional product “Sun Earth M5C” weighs 25 kg per bag, the “Bio Sun Earth” weighs only 19 kg per bag.
Installation length per bag remains the same at approximately 3 meters for strip installation (with a trench width of 0.5 m), reducing the burden of transportation and installation.

Equivalent grounding resistance reduction performance to conventional products

Grounding resistance for 3 meters of strip installation in Kanto loam soil:
Sun Earth M5C: 73Ω
Bio Sun Earth: 59Ω*
*Based on our in-house burial test results.
