Can a photovoltaic cable meet both the EN 50618 standard and the VdS certification requirements?

A photovoltaic cable can indeed meet both the EN 50618 standard and the VdS certification requirements, and here's an in - depth explanation:

1. Compatibility of Requirements

• Non - Conflicting Criteria
  • The EN 50618 standard focuses on a wide range of aspects of PV cables, including construction, electrical performance, mechanical properties, and environmental resistance. It sets the fundamental requirements for the normal operation of PV cables in various installation scenarios across Europe.
  • The VdS certification, on the other hand, is centered around fire - safety performance. It assesses how well the cable can prevent the spread of fire, its self - extinguishing capabilities, and the amount of smoke and toxic gases it emits during combustion. Since these two sets of requirements target different aspects of the cable's performance, they are generally non - conflicting.
• Complimentary Nature
  • In fact, a well - designed PV cable that meets the high - quality standards of EN 50618 can more easily be engineered to also meet the VdS certification requirements. For example, the use of high - quality insulation and sheathing materials specified in EN 50618 can contribute to better fire - retardant properties, which are crucial for VdS certification.

2. Manufacturing Capabilities

• Material Selection
  • Manufacturers can choose materials that simultaneously satisfy both sets of requirements. For conductors, they can select materials with appropriate conductivity as required by EN 50618, and for insulation and sheathing, they can use fire - retardant polymers that not only protect the conductors from environmental factors (as per EN 50618) but also have excellent fire - resistance characteristics (as per VdS).
• Production Processes
  • Advanced manufacturing processes can be employed to ensure that the cables meet both standards. For instance, precise extrusion processes can be used to ensure uniform thickness of insulation and sheathing, which is important for both electrical performance (EN 50618) and fire - safety performance (VdS). Quality control measures can be put in place at every stage of production to verify compliance with both the standard and the certification requirements.

3. Testing and Verification

• Independent Testing
  • Manufacturers can subject their PV cables to independent testing for both EN 50618 compliance and VdS certification. There are accredited testing laboratories in Europe that are equipped to perform the necessary tests for each. For EN 50618, tests may include electrical conductivity measurements, mechanical stress tests, and environmental aging tests. For VdS certification, specific fire - safety tests such as flame - spread tests and smoke - emission tests will be conducted.
• Documentation and Certification
  • Once the cables pass all the required tests, manufacturers can obtain the relevant documentation for both EN 50618 compliance (which may be used for CE marking) and VdS certification. This documentation serves as proof that the cables meet the high - quality and safety standards in both general PV operation and fire - safety aspects.
