FAQ

What are the benefits of EPR material?

Flame Retardant Cables VS Fire Resistant Cables?

How Do Water-Blocking Cables Work?

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

What is the application of Armored vs. Unarmored Cables?

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

Cable prices vary due to differences in supplier strategies, competition, raw materials, and production processes, as well as after-sales services, including installation, equipment, and ongoing support.

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 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.

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 are the benefits of EPR material?

EPR is widely used as an insulation material for electric cables due to its high dielectric strength, and it also serves as a sheathing material with excellent ozone and weathering resistance. EPR has a wide thermal range, typically spanning from -55°C to 150°C. Unlike other organic rubbers, there is no need to tin the copper conductor to prevent deterioration of the rubber.
