Features
Superior Fire Safety & High-Temperature Resistance
Constructed with non-combustible inorganic mineral insulation, these cables maintain circuit integrity during fires, ensuring critical operation for rescue and evacuation. They withstand extreme temperatures up to 950-1000℃, far exceeding standard cable limits.
High Current Capacity & Durability
Featuring high-purity copper conductors and excellent thermal conductivity, the cable supports high-current transmission efficiently. Its stable materials ensure a long service life of over 50 years.
Enhanced Flexibility For Easy Installation
Unlike traditional rigid mineral-insulated cables, YTTW/YTTWY cables offer superior flexibility. This makes them easy to bend and lay in complex environments, significantly reducing construction difficulty and costs.
Robust Environmental Protection
The cable is highly resistant to corrosion from acids, alkalis, and salts, and features a waterproof design suitable for humid or submerged conditions. It is also eco-friendly, containing no halogens, lead, or mercury.
