FAQ

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

How do you calculate the minimum bending radius of cables?

What is the validity period for the offer of cable?

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?

Is a flame-retardant cable also fire resistant?

No. A flame-retardant cable is not the same as a fire-resistant cable. A flame-retardant cable is designed to restrict the spread of fire by inhibiting combustion. Fire-resistant cables, on the other hand, maintain circuit integrity and continue to function for a specified time under defined fire conditions.

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.

Armored vs. Unarmored Cables?

Armored cables are ideal for direct burial and laying underground, offering protection against environmental factors. Unarmored cables are unsuitable for burial or use in other challenging applications and installations.

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 Do Water-Blocking Cables Work?

Water-blocking cables are essential for ensuring reliable operation in environments with high levels of moisture or frequent water contact. These cables employ water-blocking techniques to effectively prevent water ingress, protecting them from damage and prolonging their lifespan.
