FAQ

What is the operating temperature of the cable?
Is a flame-retardant cable also fire resistant?
What is the application of Armored vs. Unarmored Cables?
What is the service life of cables?
Why do cable prices vary significantly among suppliers within the same region?
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 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.
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.
What is the application of Armored vs. Unarmored Cables?
Armored cables are suitable for use in hazardous environments, such as underground installations, areas with high moisture levels, and areas prone to mechanical damage. Unarmored cables are suitable for less demanding applications, such as inside walls or other protected locations.
