Product Introduction
The Fireproof Flexible cable is a high-safety cable in the low-voltage distribution field, and this YTTW/BTTRZ/BTTZ 4-Core 4*95mm² Fireproof Flexible cable is a Low Voltage Grade Cable rated at 0.6/1KV, specially developed for harsh scenarios such as mining, railway and building power distribution. It is core-equipped with a Fire Resistant Core design, adopting high-purity oxygen-free copper conductors, mica tape and inorganic mineral composite insulation, covered with a corrosion-resistant copper sheath with grounding function. With a Class A fire resistance rating (950~1000℃) and a continuous working temperature of up to 250℃, it has excellent fire overload capacity and strong corrosion resistance. As a professional Low Voltage Grade Cable, it has a bending radius of only 6-10D, with much better flexibility than traditional rigid fireproof cables, and supports continuous production of a single length up to 1000 meters. Its multi-core structure effectively reduces eddy current loss, and the Fire Resistant Core can maintain circuit integrity and stable power supply in fire scenarios to gain critical time for personnel evacuation and fire rescue. This Fireproof Flexible cable is halogen-free and heavy metal-free, complying with RoHS environmental standards, and has a service life of more than 50 years under normal working conditions. It is the optimal choice of Low Voltage Grade Cable for photovoltaic power stations, underground projects, substations and other scenarios, and the triple protection structure of the Fire Resistant Core makes it more suitable for various low-voltage distribution projects with high safety requirements.

Core Product Advantages
Class A Fire Resistance, Fire Resistant Core for Stable Power Supply
The Fire Resistant Core adopts a triple structure of "insulation layer + mica tape fireproof layer + copper sheath". The inorganic mineral insulation material is non-combustible itself, which can maintain circuit integrity for a long time at 950~1000℃ without short circuit or power failure, meeting the high safety requirements of fire linkage systems.
Flexible & Easy to Install, Fireproof Flexible cable for Complex Working Conditions
With an exclusive small bending radius of 6-10D for Fireproof Flexible cable, it has far better flexibility than traditional rigid fireproof cables, and can be directly laid in mine roadways, railway tunnels and building interlayers, greatly reducing construction difficulty and labor costs, and improving laying efficiency.
High Temperature & Corrosion Resistance, Low Voltage Grade Cable for All Scenarios
As a 0.6/1KV Low Voltage Grade Cable, it can work continuously for a long time at 250℃, and the copper sheath is resistant to acid, alkali and salt corrosion. It can be directly applied to harsh low-voltage distribution scenarios such as underground, mining and high humidity without additional protective sleeves.
High Current Capacity & Low Loss, Maximize Transmission Efficiency
High-purity oxygen-free copper conductors have excellent thermal and electrical conductivity, with an airborne current capacity of 233A for 4*95mm² specification, meeting the demand for high-current transmission. The multi-core stranded structure effectively reduces eddy current loss, ensuring more stable power supply for photovoltaics, railways and other scenarios.
Eco-Friendly, Ultra-Long Service Life
No halogen or heavy metal added, low pollution in the whole process of production, use and disposal, complying with RoHS environmental standards. The insulation and sheath materials have high stability, with a service life of more than 50 years under normal use, greatly reducing later maintenance and replacement costs.
Ultra-Long Fixed Length, Reduce Failure Risks
Support continuous production of a single length up to 1000 meters, customizable according to engineering needs, greatly reducing the number of cable joints, lowering the risk of short circuit and electric leakage at joints, and improving the overall reliability of the power distribution system.
