IEC 61386 outlines the electrical performance requirements for conduit systems, ensuring safety and reliability in electrical installations. It covers key aspects like electrical requirements, bonding, dielectric strength, and insulation resistance.
Electrical Requirements
Conduit systems must provide reliable electrical protection for conductors and cables housed within.
- They must prevent short circuits, electrical leakage, or other hazards caused by environmental factors like moisture, dust, or physical stress.
- Electrical conduits are expected to maintain performance under varying conditions, including high voltages and fault scenarios.
Bonding
Bonding ensures electrical continuity throughout the conduit system, an essential feature for safety and effective grounding.
Eletrodutos Metálicos: Must provide a low-resistance path to ground, enabling safe dissipation of fault currents.
Conduítes não metálicos: Though not conductive, these are evaluated for their ability to integrate into bonded systems when required.
Testing involves ensuring that joints and fittings maintain electrical continuity even under stress.
Dielectric Strength
Dielectric strength measures a conduit’s ability to withstand high voltages without breakdown.
- Test Procedure: High-voltage tests are applied to the conduit system to ensure no arcing or insulation failure.
- This property is critical for installations where high voltages are present, protecting both the system and surrounding environment from electrical hazards.
Insulation Resistance
Insulation resistance assesses the ability of a conduit system to resist electrical leakage.
- This property is crucial for maintaining the integrity of the electrical circuit and preventing energy loss or potential fire hazards.
- Testing: A resistance meter is used to measure leakage under controlled voltage conditions. Conduits must meet or exceed the standard’s minimum resistance values.
IEC 61386 also focuses on the thermal properties of conduit systems, ensuring they can withstand elevated temperatures without compromising their structural integrity or performance. The tests outlined in this chapter are critical for determining a conduit system’s suitability in environments exposed to heat, such as industrial installations or locations with high ambient temperatures.
Heat Resistance of Non-Metallic and Composite Conduits
Non-metallic and composite conduits must demonstrate adequate resistance to heat to maintain reliability and safety during operation.
- The ability to resist deformation, maintain mechanical strength, and ensure uninterrupted protection of conductors at elevated temperatures is essential.
- Testing is based on the conduit’s declared compression classification and is tailored to meet these specific performance thresholds.
Heating Test
Thermal Conditioning:
Samples are placed in a heating cabinet for 4 hours ± 5 minutes at the declared temperature, with a tolerance of ±2 °C.
Temperatures are specified based on Table 2 of the standard, corresponding to the conduit’s classification.
Application of Load:
A mass, determined according to follow table, is applied to the sample using a steel rod of (6.0 ± 0.1) mm diameter.
The load is maintained for 24 hours ± 15 minutes, ensuring consistency in testing conditions.
Cooling Phase:
After loading, the sample is allowed to cool to room temperature while still under stress.
IEC 61386 Load for heating test
Classification to compression | Conduítes | Mass Tolerance +1% |
1 | Muito leve | 0.5 |
2 | Luz | 1.0 |
3 | Médio | 2.0 |
4 | Pesado | 4.0 |
5 | Muito pesado | 8.0 |
Verification Test
After cooling, the sample is evaluated for deformation and functionality:
- The load is removed, and the sample is positioned vertically.
- A specified gauge is passed through the conduit under its own weight.
- The conduit passes the test if the gauge moves freely without additional force, demonstrating that the conduit has retained its shape and internal dimensions.
IEC 61386 includes specific requirements for assessing the fire resistance of conduit systems to ensure safety in electrical installations. The standard addresses the spread of fire and the ability of conduits to resist flame propagation and prevent fire hazards.
- Glow-Wire Test: Non-metallic and composite conduit fittings undergo a glow-wire test (IEC 60695-2-11) at 750 °C to check for ignition or sustained glowing. The fittings must not ignite, and any flames must extinguish within 30 seconds.
- Flame Test for Conduits: Non-metallic and composite conduits are tested using a 1 kW flame (IEC 60695-11-2). The sample must not catch fire or, if it does, must self-extinguish within 30 seconds, with no burning of the tissue paper underneath.
- Additional Fire Characteristics: In some regions, further testing is required for low acid gas emissions from conduits during combustion, such as IEC 60754-1 or AS/NZS 2053 standard for Australia.
The fire resistance tests ensure that conduits prevent the spread of fire and maintain performance during a fire, contributing to safer electrical systems in buildings and infrastructure.
IEC 61386 specifies requirements for the external influences that can affect conduit systems, focusing on protection against ingress of foreign materials, corrosion resistance, and overall durability under different conditions.
- Degree of Protection (Ingress of Foreign Objects): Conduit systems must have adequate resistance to external influences, with a minimum protection level of IP30. Testing is conducted to ensure that no dust or foreign objects ingress into the system, in accordance with IEC 60529 standards.
- Degree of Protection (Ingress of Water): Conduits must also resist water ingress. Systems are tested to ensure that water does not enter to the extent that it forms visible droplets. Testing is performed using the oscillating tube method, also under IEC 60529.
- Resistance to Corrosion: Metallic and composite conduits (excluding screw threads) must demonstrate adequate resistance to corrosion. Compliance is evaluated through tests specific to painted and zinc-coated steel or steel composite conduits. For non-ferrous metallic and composite systems, manufacturers must provide details on their corrosion protection methods.
- Corrosion Testing: For different levels of protection (low, medium, and high), conduits undergo tests involving immersion in solutions to assess resistance to rust and other forms of corrosion. These tests ensure that the materials retain their integrity and do not exhibit excessive corrosion.
The standard ensures that conduit systems remain functional and reliable in diverse environmental conditions, providing long-lasting protection against external hazards such as dust, water, and corrosion.
Propósito: The purpose of electromagnetic compatibility (EMC) is to ensure that conduit systems do not interfere with, nor are they susceptible to, electromagnetic disturbances. EMC ensures that electrical and electronic equipment within conduit systems function properly without causing interference, or being affected by, external electromagnetic fields.
Importance:
Prevention of Electromagnetic Interference (EMI): Conduits that are part of an electrical installation must not emit harmful electromagnetic interference (EMI) that could affect nearby equipment, especially in sensitive environments like data centers or industrial control systems.
Protection from External Interference: Similarly, the conduit system should protect the wires inside from external sources of EMI that could cause malfunctions, signal distortion, or data loss. For example, in communications and high-speed data transmission systems, maintaining the integrity of signals is crucial.
Conduit Materials and Design: To meet EMC requirements, conduits may need to be designed using materials that have shielding properties or other characteristics that minimize EMI. This ensures that both the integrity of the electrical system and the safety of equipment are maintained.
