UL21307 Low Smoke Halogen - Free Fire - Resistant Cable Specification
1. Product Overview
This UL21307 Low Smoke Halogen - Free Fire - Resistant Cable is a type of cable specifically designed for big data centers, ensuring reliable performance and high - level safety in a complex electrical environment.
2. Jacket Material
The jacket material of this cable is FRPE (Flame - Retardant Polyethylene). FRPE provides excellent flame - retardant properties, while also contributing to the low - smoke and halogen - free characteristics of the cable. It helps protect the inner conductors and insulation layers from external mechanical damage, moisture, and chemical corrosion.
3. Rated Temperature
The rated temperature of this cable is 80℃. This means that under normal operating conditions, the cable can continuously and safely carry electrical current when the ambient temperature around the cable does not exceed 80℃. Operating within this temperature range ensures the stability and longevity of the cable's electrical and mechanical properties.
4. Rated Voltage
The rated voltage of the UL21307 cable is 300V. It is designed to be used in electrical systems where the voltage level between conductors and between conductors and the ground does not exceed 300V. This voltage rating determines the cable's ability to withstand electrical stress and ensures safe and efficient power transmission within the specified voltage range.
5. Product Structure
Typically, the UL21307 Low Smoke Halogen - Free Fire - Resistant Cable consists of multiple layers. Starting from the innermost part, there are one or more conductors, usually made of high - conductivity copper or aluminum, which are responsible for carrying the electrical current. The conductors are then surrounded by an insulation layer, which is made of materials with good electrical insulating properties to prevent electrical leakage. The insulation layer is further protected by the FRPE jacket, which provides mechanical strength, flame - retardant, and low - smoke halogen - free features.
6. Product Applications
This cable is widely used in big data centers for power supply to various equipment such as servers, storage devices, and network switches. Its low - smoke halogen - free and fire - resistant properties make it an ideal choice for environments where safety and environmental protection are of utmost importance. In case of a fire, the cable can continue to operate for a certain period, ensuring the continuity of power supply and minimizing the risk of data loss and equipment damage.
