ナミテイ Product Lineup

At Namitei, we handle optical fiber communication cables that can reliably transmit high-speed, large-capacity information without leaking to the outside. The "Optical Fiber Protection Special Wire for Submarine Cables" is a product designed to protect the core optical fiber. It not only withstands high water pressure of up to 8000 meters in depth and 800 atmospheres, but also prevents cable cuts caused by ship anchors, fishing nets, and sharks. In the event of an accident on the seabed, it prevents seawater from entering the cable within 100 meters! 【Features】 ■ For submarine cables ■ Withstands high water pressure of up to 8000 meters in depth and 800 atmospheres ■ Prevents cable cuts caused by ship anchors, fishing nets, and sharks ■ In the event of an accident on the seabed, prevents seawater from entering the cable within 100 meters *For more details, please refer to the PDF document or feel free to contact us.

An article about our "Optical Fiber Protection Specialty Wire for Undersea Cables" has been published in the Industrial Economic Newspaper! In the midst of the recession known as "Iron Cold" in 1984, when our company was still called "Naniwa Seikui," we received an order from a steel trading company in Tokyo requesting, "Please make a fan-shaped specialty wire by splitting a pipe into three vertically." A few days later, President Murao was surprised when he saw the drawings that arrived. It was the first order for a fan-shaped iron wire, and on top of that, they requested a tolerance of within plus or minus five thousandths of a millimeter. At that time in the industry, a tolerance of about one-tenth of a millimeter was the norm, and they were demanding an unprecedented level of precision, with a length of 1000 meters as well. The delivery date was specified for just two weeks later. * The full text is available at the link below. * For more details, please refer to the PDF document or feel free to contact us.

Our company is committed to "modern manufacturing," starting with the production of nails and evolving through various transformations, including the production of copper shaped wires, growing alongside the times. We manufacture a variety of shaped wires with different cross-sectional shapes, as well as related components. Based on the manufacturing technology of shaped wires that we have cultivated over many years, we cater to a wide range of needs, from everyday life-related fields such as automotive, construction, civil engineering, home appliances, and plants, to global and cutting-edge areas like submarine cables.

【Optical Fiber Protection Shaped Wire for Submarine Cables (3 Split Pieces)】 ◆ By combining three 120° fan-shaped wires, a pipe shape is formed. ◆ It is possible to directly house multi-core optical fibers inside. ◆ It withstands high water pressure environments and also functions as a tensile strength component of the cable. 【What is Shaped Wire?】 Metal materials processed into various cross-sectional shapes rather than standard cross-sectional shapes. ～What Can Be Achieved with Shaped Wire～ ◆ Flexible design (lightweight, increased surface area, surface properties, strength, hardness control) ◆ Improved production efficiency (continuous production from coils, near-net shaping) ◆ Environmentally friendly (SDGs, carbon neutrality)
