FAQ

What temperature can high-temperature resistant cables reach, and what are their application scenarios?

How Do Water-Blocking Cables Work?

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

Is a flame-retardant cable also fire resistant?

Flame Retardant Cables VS Fire Resistant Cables?

What is the length tolerance for cables?

The tolerance for the power cable is 0 to +0.5%. For the bare conductor, the tolerance is ±5%.

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.

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.

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.

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.
