FAQ

Armored vs. Unarmored Cables?
How long is the validity period of cold shrink cable accessories?
What temperature can high-temperature resistant cables reach, and what are their application scenarios?
Why do cable prices vary significantly among suppliers within the same region?
How Do Water-Blocking Cables Work?
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 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 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 is the validity period for the offer of cable?
Typically, the offer is valid for 7 to 30 days, and the price will be adjusted according to the cost of raw materials and the exchange rate.
