Abstract

The 60502-2 standard is an important specification in the field of power cables. This article provides a detailed explanation of 60502-2 from four aspects: scope, construction, electrical properties, and testing requirements. Understanding this standard is crucial for professionals in the cable industry to ensure the quality and safety of power cables.

1. Scope

The scope of 60502-2 encompasses various types of power cables used for electricity transmission and distribution systems. It includes cables with rated voltages up to 30 kV and covers both indoor and outdoor installations. The standard defines the general requirements for these cables, including their design, materials used, manufacturing processes, and performance characteristics.

Furthermore, it specifies the specific cable types covered by this standard such as single-core or multi-core cables with copper or aluminum conductors. It also addresses different insulation materials like PVC (Polyvinyl Chloride), XLPE (Cross-linked Polyethylene), or EPR (Ethylene Propylene Rubber).

In summary, 60502-2 sets out a comprehensive framework that ensures uniformity in manufacturing practices while meeting safety standards for power cable applications.

2. Construction

The construction requirements outlined in 60502-2 define how power cables should be designed and manufactured to meet specific performance criteria. These criteria include mechanical strength, resistance to environmental factors such as moisture or temperature variations, fire resistance properties, and electrical conductivity.

This section specifies details about conductor sizes ranging from small cross-sectional areas suitable for low voltage applications to larger sizes required for high voltage transmission lines. It also covers aspects like insulation thicknesses based on voltage ratings to ensure proper dielectric strength.

Furthermore,the use of protective layers such as metallic screens or armor is addressed depending on the application environment. Overall,the construction requirements aim at providing durable yet flexible power cables capable of withstanding various operating conditions while maintaining electrical integrity throughout their service life.

3.Electrical Properties

This aspect focuses on defining key electrical parameters that determine the performance capabilities of power cables according to their intended usage scenarios.

The first parameter addressed is conductor resistance which affects energy losses during transmission.

Another important property discussed is insulation resistance which indicates how well a cable can withstand leakage currents.

Capacitance between conductors influences signal propagation characteristics while reactance determines impedance levels at different frequencies.

Moreover，dielectric strength specifications establish minimum values necessary to prevent breakdowns under normal operating conditions

In addition，short-circuit current ratings are defined based on thermal stability considerations
