Low Voltage Mineral Insulated Cable YTTW Fire Resistant Cable 0.6/1kV
YTTW Fire Resistant Cable 0.6/1kV Low Voltage - Flexible Mineral Insulated Cable
Are you looking for a reliable low-voltage cable that ensures uninterrupted power supply even under extreme fire conditions? Our flexible YTTW mineral-insulated cables exceed global safety standards, providing superior fire resistance, corrosion resistance, and durability for your critical applications. They are ideal for any location with extremely high safety and reliability requirements, such as high-rise buildings, transportation hubs, industrial facilities, and data centers.
- Superior Fire Resistance: Maintains power supply for 3 hours at 950°C (compliant with BS 6387 Class C) and resists water splashes and mechanical impacts during a fire. This ensures critical systems operate stably when needed most.
- Low-Voltage Stability: Designed for 0.6/1 kV and 450/750 V, providing stable performance for both low-load and high-load low-voltage power distribution systems.
- Exceptional flexibility: Multi-core copper conductors and a corrugated copper sheath allow for a minimum bending radius of up to 15 times the cable's outer diameter, simplifying installation in confined or complex spaces.
- Halogen-free and environmentally friendly: All inorganic materials do not produce toxic fumes or harmful gases in the event of a fire, protecting personal safety and reducing subsequent losses.
- Long service life: The inorganic insulation layer is resistant to aging, corrosion, and rodents, with a service life comparable to that of the building itself, thus reducing long-term maintenance costs.

Our YTTW cables are manufactured using a rigorous six-step process to ensure superior quality:
- High-purity copper wire drawing and stranding: Producing flexible, highly conductive copper wire for optimal installation flexibility.
- Mineral insulation: Precision winding with high-temperature resistant mica tape to form a uniform, fire-resistant insulation layer.
- Fiberglass Filling: Uniformly filled with alkali-free fiberglass, enhancing fire resistance and stability.
- Longitudinal Winding and Copper Strip Welding: Seamless copper strip welding forms a dense, corrosion-resistant sheath.
- Corrugated: Produced with a corrugated copper sheath, improving flexibility and bending strength.
- Strict Quality Control: Comprehensive testing of electrical performance, fire resistance, and appearance according to international standards.
A: Our MOQ is 100 meters. For larger orders, we offer discounts and customized solutions.
A: Yes, we provide free samples. You only need to pay the express delivery fee, which will be deducted from your order amount.
A: Fully compliant. Our cables conform to GB/T 34926-2017, JG313-2014, BS 6387:2013, and BS 8491:2008 standards. We are happy to provide the relevant certificates if needed.
A: YTTWY cables use a low-smoke halogen-free (LSZH) outer sheath, which complements the structure of YTTW cables, making them more suitable for direct burial and outdoor applications, and providing stronger corrosion resistance.
A: The delivery time for standard sizes is 7-15 working days. The delivery time for customized sizes depends on specifications and quantity—we will send you a detailed delivery schedule after order confirmation.
