Purchasing an electrical cable may seem simple, but an incomplete specification can lead to technical problems, rework, and even losses in your project. To ensure that the product exactly meets the application requirements, it is essential to provide clear and standardized information to the supplier. In this article, you will understand how to specify electrical cables correctly and avoid common mistakes when comparing quotes.
Medium voltage cables: pay attention to the shielding.
For electrical cables above 1,000 V, it is also essential to specify:
- Metal armor section
Depending on the installation environment, some additional features may be essential:
- Moisture barrier
- Colored coating (when not black)
- Protection against rodents and termites
- Metal armor for mechanical reinforcement.
The danger of an incomplete specification.
A vague specification can lead to a classic problem: you receive different quotes for products that look the same—but aren’t. This makes price comparison difficult and can result in choosing an unsuitable cable.
Result:
- Risk of failure
- Reduction in service life
- Security issues
