The installation of electric trace systems in industrial environments requires not only technical knowledge, but also compliance with standards and regulations that guarantee safety, energy efficiency and durability of the solution. No brazil, various regulations guide the choice, installation and maintenance of these systems.
This article presents an updated overview of the main standards and good practices that should be considered in industrial projects, especially in those who operate in severe temperature conditions, humidity, aggressive or risk -risk atmospheres.
1.NR-10: Safety in Electrical Installations and Services
NR-10 is the main regulatory standard that deals with security in electrical installations. Applies directly to the installation of electric trace and defines obligations as:
- Training of Electrical Security Professionals;
- Preparation of electric medical record and work procedures;
- Adoption of risk control measures, as isolation, Shock protection and proper grounding;
- Use of Personal Protective Equipment (EPIs) and collective.
In electric trace systems, It is essential that the entire installation is projected, executed and maintained in accordance with NR-10.
2. NR-12: Safety at Work in Machinery and Equipment
In industrial environments that use electric trace coupled to machines or tanks, NR-12 should be considered. It requires:
- Assessment of accidental contact risks with heated parts;
- Physical barriers, SIGNALING AND EMERGENCY SYSTEMS;
- Interlocking and electrical protections to avoid failures.
The standard also deals with ergonomics and accessibility for safe maintenance of systems.
3. ABNT NBR 5410: Low voltage electrical installations
This is the norm most directly related to the sizing and execution of low voltage electrical installations (Up to 1000V), including electric trait.
It establishes criteria on:
- Dimensioning of cables and protections;
- Grounding and Equipotentialization;
- Circuit breakers and protection devices;
- Criteria for wet areas, with risk of corrosion or special atmospheres.
Any electric trace project should follow the criteria of this standard, that defines safety standards and minimum performance for electrical installation as a whole.
4. ABNT NBR 15218: Thermal insulation of pipes and industrial equipment
Although it does not specifically deal with the electric trait, This standard is essential in sizing industrial thermal systems. She guides about:
- Types and thickness of thermal insulators;
- Materials suitable for different temperature ranges;
- Requirements for heat containment and energy efficiency.
The correct combination between electric trace and isolation is indispensable to avoid waste of energy and ensure thermal performance.
5. Manufacturer recommendations and installation procedures
Each electric trace cable manufacturer provides its own recommendations for:
- Minimum curvature;
- Cable positioning in relation to the pipe (usually in the lower position);
- Need for extra cables at critical points (flanges, valves, supports);
- Compatible connections and terminals.
Following these guidelines is essential to ensure system durability and maintain product warranty.
6. Good practices for compliance and efficiency
Beyond the norms, It is recommended to follow good installation practices:
- Use of fixing tapes and terminals suitable for the temperature range;
- Protection of connections with thermoencolhable tubes and prohibited derivation boxes;
- Periodic inspections through thermography and insulation tests;
- Detailed Project Documentation, with specifications, sketches and constructive methods.
