Cable management systems are crucial for the safety and reliability of electrical installations across various industries. Cabstrut, a recognised manufacturer of cable ladders and trays, stresses product quality and compliance by carefully testing its products against international standards. One important standard is IEC 61537:2023, also adopted in South Africa as SANS 61537:2023.
Overview of IEC 61537:2023 (SANS)
IEC 61537:2023 specifies requirements and tests for cable tray and ladder systems designed to support and secure cables and, where necessary, other electrical equipment in electrical installations. The standard covers mechanical strength, electrical continuity, corrosion resistance, and safety, ensuring products are suitable for their operating environments.
Cabstrut’s Commitment to Quality and Compliance
Cabstrut’s customers in South Africa and throughout Africa, where international standards are upheld, require verification of this IEC standard. This comprehensive specification mandates testing under conditions that closely resemble real-world applications. The recent addition of a method to test cable ladders and trays both horizontally and vertically distinguishes this process.
Cable ladders designed specifically for vertical use were first developed and marketed in South Africa and are now widespread across Africa. Previously, the cable management industry relied on various, often unspecified, test methods. Conducting tests in accordance with this specification allows Cabstrut to confidently publish reliable Safe Working Loads.
Cabstrut offers cable management solutions that consistently meet or exceed industry standards. By following IEC 61537:2023 (SANS) testing methods, Cabstrut guarantees its cable ladders and trays deliver reliable performance, safety, and durability.
State-of-the-Art Load Testing Facility
Cabstrut’s advanced load testing facility demonstrates its dedication to precise, specification-based testing. The facility measures 12 metres in length, 1.36 metres in width, and 3.05 metres in height, enabling testing of cable ladders and trays over spans up to 6 metres, as specified by IEC 61537:2023 (SANS).
This involves testing a total ladder length of 14.9 metres in specific configurations. Load is applied by adding precisely determined weights, considering the fixing method, fasteners, the loading system, and the weights themselves. All weights used in testing have been independently verified by Mining and Surface Certification (MASC), ensuring full traceability and credibility.
During tests, weights are accurately measured at each load point, metre, span, and along the entire length of the load. Deflection measurements are recorded electronically using draw-wire sensors for vertical movement and linear actuator sensors for horizontal movement, both with an accuracy of 0.1 mm.
The facility’s adaptable design allows for adjustment of load and deflection points, supporting various span needs. It is suitable for testing both vertical and horizontal loads. A digital recording station captures all data in real time according to set parameters. This facility fully complies with IEC standards and will also support future testing of other load-bearing products.
Documentation and Certification
After successful testing, Cabstrut documents the results and issues certificates of conformity. This documentation confirms that products have been independently assessed to meet the requirements of IEC 61537:2023 (SANS), assuring customers of quality and safety.
Conclusion
By thoroughly testing cable ladders and trays to IEC 61537:2023 (SANS), Cabstrut demonstrates its commitment to safety, performance, and customer satisfaction. Specifiers, contractors, and users can rely on Cabstrut’s solutions to meet leading international standards.
