PRODUCT DETAILS

This product is suitable for power transmission in power lines with a rated voltage of 0.6/1KV and below. Flame-retardant wires and cables are difficult to ignite and have the ability to prevent or delay the spread of flames. They are suitable for laying in various situations where flame retardancy is required, such as high-rise buildings, hotels, hospitals, subways, nuclear power plants, power plants, mines, petroleum, and chemical industries.

Flame-retardant wires and cables refer to cables that, when burned under specified test conditions, have the characteristic of limiting the spread of flames to a limited area. After the ignition source is removed, the residual smoke and embers self-extinguish within a limited time.

Flame-retardant cable

Flame retardant grade	Fire supply temperature	Fire supply time	Non-metallic material volume of bundled cables	Carbonization height	Self-extinguishing time	Applicable products
A	≥815℃	40min	≥7 liters/meter	≤2.5 meters	≤1 hour	Flame-retardant cable
B	≥815℃	40min	≥3.5 liters/meter	≤2.5 meters	≤1 hour
C	≥815℃	20min	≥1.5 liters/meter	≤2.5 meters	≤1 hour	Flame-retardant cable
D	≥815℃	20min	≥0.5 liters/meter	≤2.5 meters	≤1 hour	Flame-retardant insulated wire

Usage Characteristics

The rated voltage U0/U of flame-retardant cables is 0.6/1KV; the rated voltage U0/U of flame-retardant control cables is 450/750V; the rated voltage U0/U of flame-retardant wires and cables is 450/750V and below.

The long-term allowable operating temperature of PVC insulated cables is no more than 70℃; the long-term allowable operating temperature of XLPE insulated cables is no more than 90℃.

The ambient temperature during installation should not be lower than 0℃.

Minimum Bending Radius During Cable Installation

For flame-retardant wires with an outer diameter (D) less than 25mm, the allowable bending radius of the cable should not be less than 4D; for outer diameters (D) of 25mm and above, the allowable bending radius of the cable should not be less than 6D.

Flame-retardant and fire-resistant control cables: For cables without armor, the minimum diameter should be no less than 6 times the cable's outer diameter; for cables with armor or copper tape shielding, the minimum diameter should be no less than 12 times the cable's outer diameter.

FAQ

What is the typical delivery time for cables? Can you expedite the delivery?

Standard delivery times: ① Ordinary cables (e.g., YJV, VV series): 15-25 days; ② Specialty cables (e.g., high-temperature resistant, explosion-proof): 25-40 days; ③ Large-volume orders (over 10,000 meters): 30-50 days. Expedited delivery is available, subject to the following conditions: ① Sufficient raw material inventory; ② Customer payment of expedited fees (calculated based on the number of expedited days); ③ Expedited delivery can generally shorten the delivery time by 5-10 days, subject to confirmation with the supplier.

Who determines the HS code for exported cables? Does the customer need to confirm it?

The HS code is mainly determined by the supplier based on the cable type and specifications (e.g., 8544.49 for power cables and 8544.70 for communication cables). However, customers need to verify that: ① the HS code provided by the supplier must be consistent with the actual cable specifications and the customs clearance requirements of the destination country; ② customers can verify the accuracy of the HS code based on their own customs clearance experience to avoid customs clearance delays, fines, or impact on tariff payments due to incorrect coding.

Can you provide samples?

Samples are available. Standard samples (1-5 meters) are free, with shipping costs borne by the customer. Customized samples require a small sample production fee, which can be deducted from the purchase price for bulk orders.

What is the minimum order quantity (MOQ) for exported cables?

Minimum order quantity (MOQ) depends on the cable type: ① Standard power and communication cables: MOQ is typically 1000 meters/model; this can be negotiated for bulk purchases. ② Specialty cables (high temperature resistant, explosion-proof, etc.): Due to complex manufacturing processes, MOQ is generally 500 meters/model.
