Fujikura’s eco wires and cables are manufactured with unique new eco materials produced using its sophisticated eco-technology. They differ from conventional eco wires and cables in their use of lighter specific gravity sheath (approx. 1.1), and so can be distinguished from polyvinyl chloride sheath which has a specific gravity of approx. 1.4. They also provide clearer coloring, weather resistance and flexibility equal to or even better than polyvinyl chloride.
Fujikura supplies environment-friendly and easy-to-recycle eco wires and cables.
Easy to recycle:
Because sheath of lighter specific gravity (1.1) is used, separation from wires or cables with polyvinyl chloride sheath based on specific gravity is now possible. This facilitates material and thermal recycling processes.
Environment-friendly and disaster-proof to provide safety:
2-1 No hazardous gases are generated
The products are halogen-free and so generate no toxic halogen-containing gases when burnt.
There are also no constituents that could generate dioxins.
2-2 Low smoke emission rates
The amount of smoke emitted upon combustion is less than half that of polyvinyl chloride sheath. This helps prevent secondary disasters due to exposure to smoke.
2-3 No corrosive gases generated
The products are halogen-free and so generate no corrosive gases.
2-4 Contains no heavy metals such as lead
2-5 Excellent flame retardation capability
Fujikura’s eco wires and cables have flame retardation rated to pass the 60 degree flame test of JIS C 3005.
Eco wires and cables rated to pass the vertical-tray flame test of JIS C 3521 are also available.
Excellent weather resistance:
The weather resistance required by light-colored materials has been greatly improved.
UV test results of yellow-colored test pieces are shown in Fig. 10. After 200 hours of accelerated test (equivalent to outdoor exposure for 10 years), the eco materials showed almost no deterioration of characteristics.
Color degradation was minimal.
Greater current rating than conventional polyvinyl chloride insulated wires or cables:
Because the heatproof temperature of the insulation is higher with the eco materials (75°C) than with polyvinyl chloride (60°C), eco wires or cables have a greater current rating. (*) The rate of deformation of flame retardant polyethylene in a temperature region below the allowable level of 75°C is better than that of polyvinyl chloride. However, the rate of deformation increases above 90°C. For applications in such a temperature region, wire sizes must be carefully selected taking into consideration such factors as ambient temperatures or current reduction ratio in multiple wire installations (refer to JCS 131B published by Japanese Electric Wire & Cable Makers’ Association).
Eco materials have as good flexibility as polyvinyl chloride.
Eco materials can be colored as vividly as polyvinyl chloride.
