In modern industrial systems, protection against electromagnetic interference (EMI) is a key requirement. Choosing a shielded cable can make a real difference in terms of safety, reliability, and system longevity. But when is it truly necessary? And what solutions does the market offer?
In this article, we explore the main application contexts, the types of shielding available, and some practical examples from the Sada Cavi product range.
Why use a shielded cable?
- Protection against electromagnetic interference (EMI)
- Integration in mixed environments (power + signal)
- Compliance with EMC regulations
- Reliability over long distances or in systems with inverters
Types of Shielding
- Copper braid: good coverage, flexible
- Foil/aluminium tape: effective protection at high frequencies, ideal for signal transmission
- Double shielding: for high-interference environments
Examples from the Sada Cavi Catalogue

When is a shielded cable essential?
- In the presence of inverters or frequency converters
- For sensitive signals (e.g. encoders, sensors)
- Close to power cables or high-voltage systems
- In industrial environments with interference risk or intermittent faults
Shielded cables are not just an optional choice—they are a strategic component to ensure efficiency and safety. Sada Cavi offers a wide range of solutions for every need, from fixed installations to flexible applications.
