FAQ

Is a flame-retardant cable also fire resistant?

Longitudinal Water Blocking vs. Lateral Water Blocking?

How Do Water-Blocking Cables Work?

What are the benefits of EPR material?

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

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.

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.

What are the weight limits for different types of packages?

The weight limit for a wooden drum or steel wooden is 5,000 kg, and for a steel drum, it is 10,000 kg.

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.

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.
