FAQ

Flame Retardant Cables VS Fire Resistant Cables?

What are the weight limits for different types of packages?

Armored vs. Unarmored Cables?

What is the purpose of a metallic shield in MV and HV cables?

What is the validity period for the offer of cable?

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.

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.

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 operating temperature of the cable?

The operating temperature of a cable is determined by the insulation and sheathing material. PVC has a range of -15°C to 70°C, XLPE can reach up to 90°C, while silicone rubber can handle temperatures from -60°C to 180°C.
