FAQ

What temperature can high-temperature resistant cables reach, and what are their application scenarios?

How long is the validity period of cold shrink cable accessories?

What is the service life of cables?

What is the operating temperature of the cable?

Why do cable prices vary significantly among suppliers within the same region?

What is the service life of cables?

The design life of power cables is typically 20 to 30 years; however, this can vary significantly based on factors such as installation, environmental conditions, and the quality of the cable.

Flame Retardant Cables VS Fire Resistant Cables?

Both types of cables are crucial in enhancing the likelihood of escape and survival in the event of a fire and are often confused with one another. However, there is a fundamental distinction between flame retardant cables and fire resistant cables. Flame retardant cables are engineered to inhibit the spread of fire to adjacent areas. On the other hand, fire resistant cables are specifically designed to preserve circuit integrity and ensure functionality during a fire, under specified conditions, aiding both evacuees and firefighters.

What is the minimum order quantity for the product?

The minimum order quantity for low and medium voltage cables is 200 meters, whereas for high voltage cables, it is 2000 meters. Should the order quantity fall below the MOQ, however, if the factory has stock, we can still supply it.

How long is the validity period of cold shrink cable accessories?

The validity period for most cold shrink cable accessories is typically 3 years from the date of manufacture, provided they are stored under recommended conditions. These conditions usually include controlled humidity and temperature ranges.

What temperature can high-temperature resistant cables reach, and what are their application scenarios?

High-temperature resistant cables are engineered to function within a wide temperature range, spanning from -50°C to +260°C, depending on the cable's specific type and construction. Silicone rubber-insulated cables can withstand temperatures up to 180°C, whereas fluoroplastic insulated cables are designed to endure temperatures as high as 200°C to 260°C over extended periods. They are widely used in steel metallurgy, power, petrochemicals, aerospace, and industrial kilns for power transmission and equipment control in high-heat environments.
