The actual area is not critical nor is it a parameter that must be measured. The peak Australian electrical industry body, the National Electrical and Communications Association NECA and the world’s leading electrical industry information portal Voltimum have joined forces nzd an effort to raise awareness and educate users of the dangers of using product that is not compliant to Australian Standards.

Smaller diameter conductors, such as compacted, or the larger diameter non-compacted conductors, do not matter. A 35mm2 copper conductor, for example, does not need to have 35mm2 of copper in it.

When looking at the impact of non-compliant resistance 50002 the current rating of a cable, its impact is relatively small, as its current rating is proportional to the inverse of the square root of resistance. Take the online training and add your voice to this campaign!.

A variety of cable insulating materials exists in the cable manufacturing industry, all having differing properties, but all having the primary attribute of being suitable as an electrical insulating material.

Subscribe to receive the lastest news from the electrical industry brought to you by Voltimum. It only needs to meet the specified resistance value. They may soften, but will not flow. Join the fight against non-compliant products! In the case of insulation thickness, this varies with material type and conductor size. These performance requirements are largely based on the mechanical properties of the materials used in cables.

Privacy Policy Terms of Service. The insulation thickness on large conductor sizes is greatest due to the greater risk of mechanical damage during handling of large and heavy cables. Then there is the material that is in contact with the conductor.

What may be not so obvious is how the thickness is actually measured. Keep up to date with latest from nnzs campaign through our Facebook page!

Modern manufacturing techniques have seen the introduction of automated electronic measurement systems to replace manual methods that provide a significant improvement in repeat accuracy. The following sections refer to a range of tests that are conducted on cables to ensure compliance. Introduction In this article I will try to unravel some of the less known aspects of cable compliance with the overall aim to give the user the correct information to make better informed decision when selecting cable products.

To confirm that a cable can hold its rated voltage the cable is subjected to the following checks and test:. Their differences lie in their cost, processability, dielectric performance, mechanical strength and flexibility to name a few. See examples in Figure 1 for various types of extrusions.

Only the electrical resistance is mandatory. And neither is the diameter of a conductor important as far as compliance is concerned. The standards referred to in details the test method used to conduct each test.

PE has significantly greater dielectric strength compared to PVC, which is a blend of a number of ingredients of which Poly Vinyl Chloride is one. In terms of cables the wiring rules makes direct reference to Australian and New Zealand Standards as the principle means to ensure that its scope is fulfilled.

To be continued in Part 2. This is a common testing principle where the test object is subjected to a higher stress than it would normally be expected to operate at, with the intention to flush out extrusion defects or weaknesses in the insulation materials. There has been much publicity recently about the recall of non-compliant building cables, but what does compliance actually mean as far as a cable is concerned and how does it actually relate to performance?

The improved nze properties of XLPE is a result of the chemical makeup of the material, being almost exclusively polyethylene. It will be fairly obvious that the thickness of the insulation and sheath material must be aligned with the typical use of the product. Cross-Linked materials are more thermally stable compared to Thermoplastic materials and will not flow when subjected to high operating temperatures.

Voltage tests performed on cables are done at higher than normal operating levels. This document defines the principles upon 50002 electrical installations must be designed and installed in order to protect people, livestock and property from the risk of electrical shock, fire and physical injury hazards.
