The following sections refer to a range of tests that are conducted on cables to ensure compliance. This document defines the principles upon which 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. See examples in Figure 1 for various types of extrusions.

In the first part of this article I will address the first dot point only. To confirm that a cable can hold its rated voltage the az is subjected to ass following checks and test:. It only needs to meet the specified resistance value.

AS/NZS 5000.2:1999

Smaller diameter conductors, such as compacted, or the larger diameter non-compacted conductors, do not matter. 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. Modern manufacturing techniques have seen the introduction of automated electronic measurement systems to replace manual methods that provide a significant improvement nnzs repeat accuracy.

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 in an effort to raise awareness and educate users of the dangers of using product that is not compliant to Australian Standards.

This is a legally mandated document, and therefore the risk of non-compliance is not only unsafe it is also illegal.

The following briefly describes each of the above tests, their purpose and how they relate to the mechanical performance of the cable in terms of installation and long term operation of the cable. Join the fight against non-compliant products!

To be continued in Part 2. They may soften, but will not flow. A variety of cable insulating materials exists in the cable manufacturing industry, all having differing properties, but mzs having the primary attribute of being suitable as an electrical insulating material.

Cross-Linked materials ad more thermally stable compared to Thermoplastic materials and will not flow when subjected to high operating temperatures. The manner in which compliance of these materials is confirmed is complex and will be covered in some detail under the discussion later on insulating materials.

Type of Business Contractor emp. It will be fairly obvious that the thickness of the insulation and sheath material must be aligned with the typical use of the product. When looking at the impact of non-compliant resistance on 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.

In terms of cables the wiring 500.02 makes direct reference to Australian and New Zealand Standards as the principle means to nze that its scope is fulfilled.

The improved electrical properties of XLPE is a result of the chemical makeup of the material, being almost exclusively polyethylene. The actual area is not critical nor is it a parameter that must be measured. The standards referred to in details the test method used to conduct each test. This first part looks at the nzss and physical dimensional testing nz for cables, whilst the second part looks at the range of material tests that cable materials must meet to enable compliance to be obtained.


In the case of insulation thickness, this varies with material type and conductor 500.2. These performance requirements are largely based on the mechanical properties of the materials used in cables. The measurement method described above has traditionally been carried out by manual methods and is therefore subject to human error.

Due to the level of detail required to address this topic it will be presented in two parts. Their differences lie in their cost, processability, dielectric performance, mechanical strength and flexibility to name a few.

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? Some of the common cable insulating materials are listed below:.

Ability to Carry Rated Current The ability of an electrical cable to carry its design electric current is largely dependent on the electrical resistance of the conductor. The insulation thickness for LV cables is not primarily based on electrical requirements, but more on mechanical considerations.

Only the electrical resistance is mandatory. Keep up to date with latest from this campaign through our Facebook page!

These are the two measurements that compliance is confirmed and is required by nearly all cable standards today. Take the online training and add your voice to this campaign!.
