Cable ties and cable tie bases are essential components in electrical installations in the UK. They serve as a means of anchoring, securing, and organizing wiring in a safe and efficient manner. In accordance with the 18th edition of the British Standards Code of Practice for Electrical Installations (BS 7671), the use of cable ties and cable tie bases in electrical installations must comply with specific requirements and regulations.
Firstly, it is important to note that cable ties and cable tie bases must be made of suitable materials that meet the rigors of the environment in which they will be installed. The 18th edition of BS 7671 requires that cable ties and cable tie bases meet certain mechanical and environmental performance requirements. Cable ties and their bases must be suitable for both interior and exterior applications, as well as for use in harsh or hazardous environments where exposure to chemicals, ultraviolet radiation, and other substances may occur.
The standard specifies that cable tie bases must be made of materials that are corrosion resistant and non-hygroscopic, meaning they do not absorb moisture. This is important because moisture and corrosion can degrade the integrity of electrical installations over time, leading to safety hazards and potential equipment failure. Furthermore, cable ties must be of sufficient tensile strength, able to withstand the weight of the cables they support without failure, and must not cause damage to the cable insulation during installation or use.
Additionally, the spacing and routing of cable ties must also be in accordance with the 18th edition of BS 7671. For example, cable ties should not be spaced too closely together, as this can cause electrical interference and increase the risk of short circuits. On the other hand, cable ties must not be spaced too far apart, which can lead to cable sag and increased stress on the wiring and connections. Therefore, cable ties should be positioned to prevent cable sag, but not so tightly that they deform or pinch the cables.
Another consideration is the use of cable ties in hazardous locations. The 18th edition of BS 7671 requires that cable ties used in hazardous locations must be of a suitable material that is resistant to the specific hazards present in that environment. This may include exposure to chemicals, high temperatures or corrosive substances.
In conclusion, the use of cable ties and cable tie bases in electrical installations in the UK must adhere to the specific requirements set out in the 18th edition of BS 7671. The choice of material, mechanical and environmental performance requirements, and spacing and routing must be carefully considered to ensure the safety and efficiency of the installation. By following these regulations, electrical professionals can ensure that cable ties and cable tie bases are used effectively to secure and organize wiring while minimizing the potential for hazards.
