In the world of aerospace, every detail counts. From the smallest components to the largest structures, aerospace engineers and manufacturers strive for perfection in every aspect of their products. One of the critical components that require special attention is the electrical wiring system of an aircraft. Every wire must be precisely installed and routed, and the insulation and shielding must meet the highest standards to ensure safety and reliability.
One of the essential steps in wiring installation is the stripping of the electrical cables. The process of stripping refers to the removal of insulation or shielding from the end of a wire, leaving the conductor exposed to facilitate termination or soldering. Stripping must be done carefully, especially in high-performance applications such as aerospace, to avoid damaging the conductor or introducing contaminants that can compromise the integrity of the wiring.
The EN 2812 standard defines the requirements for the stripping of electric cables in aerospace applications. The standard is part of the broader EN 8XXX series, which covers various aspects of aerospace wiring and cabling, including materials, construction, installation, and maintenance. EN 2812 specifies the minimum requirements for the stripping of insulation and shielding from wires and cables used in aerospace applications.
The standard covers various types of cables used in aerospace, including single-core, multi-core, and shielded cables. It outlines the requirements for the stripping tool, including the blade type, size, and angle. It also specifies the maximum length of insulation or shielding to be stripped, based on the wire's diameter and type. The standard also defines the criteria for inspecting the stripped end of the cable, such as the absence of nicks, scratches, or cracks on the conductor.
EN 2812 also emphasizes the importance of training and qualification for personnel involved in cable stripping operations. The standard requires that personnel responsible for stripping electric cables must be adequately trained and qualified to perform this task. The training program must cover the relevant electrical and mechanical principles, as well as the specific procedures and techniques for stripping aerospace cables.
The EN 2812 standard is essential for ensuring the safety and reliability of aerospace wiring systems. It sets clear guidelines and specifications for the stripping of electric cables, minimizing the risk of damage or contamination. By adhering to this standard, aerospace manufacturers and service providers can ensure that their wiring systems meet the highest quality standards and comply with industry regulations and standards.
In conclusion, the EN 2812 standard is a critical component of the aerospace wiring system. It defines the requirements for the stripping of electric cables, ensuring that this delicate and essential operation is performed correctly and safely. By following the guidelines specified in this standard, aerospace manufacturers and service providers can maintain the highest levels of quality and reliability in their wiring systems, contributing to the overall safety and performance of their aircraft.
