IEC 60287

Fast track your power cable selection and sizing knowledge!

Master Cable Sustained Current Ratings According to IEC 60287

Gain know-how, and insights on how cable thermal sizing works. IEC 60287 Cable Thermal Sizing, is the course that can make give you a full understanding and confidence to be able to apply the principals given in the standard.

Are you...

comfortable with cable sizing, but want to expand your knowledge
interesting in IEC 60287, but don't know the details
want to determine the current capacity of cables more accurately
need to evaluate cable performance in unusual situations

... let our online course enrich and build your knowledge.

IEC 60287 Cable Thermal Sizing, a 3-week online course will help you gain an in-depth understanding of Standard and it's application. This course is for all practising engineers, contractors and cable users.

In our Cable Master Class, you will learn about

types of cables and construction standards from low voltage to 33 kV
calculation of dc and ac resistance
calculation of thermal properties of cable-layers and the environment
the thermal capacity of dc and ac cables in air and buried

Throughout the course, we work with you to provide support, answer questions and give feedback on a weekly basis. The goal is to give you the cable knowledge to be able to perform with your peers and at the very highest level.

Note: this course is open to anyone, but some previous power cable experience is required. Some pre-existing knowledge of electrical engineering is required. Course participants should already understand the basics like resistance, reactance and impedance, and single-phase and three-phase systems.

Course Outline

During week 1 you will learn how the course works and review the basics of cables. Weeks 2 to five will build on this, giving you all the tools you need to become a cable pro.

Week 1 - Cable Review

Cable Construction - understand the construction of low and medium voltage cables
Standards - investigate cable construction, application and sizing standards
Insulation - learn about different insulation, their properties and effect on cable life
Thermal Rating - introduction to cable thermal rating

Week 2 - IEC 60287 Thermal Analysis

Sustained current capacity
DC & AC resistance of conductors
Dielectric loss
Sheath, screen and armour loss

Week 3 - IEC 60287 Thermal Resistance

Thermal resistance - T1, T2 & T3 [insulation, bedding, sheath]
Thermal resistance - T4 [surrounding medium]
Direct solar radiation - accounting for in calculations
Cable troughs - accounting for in calculations

The course is online, with continual content released during the 3-week period. You will be enrolled in our virtual classroom, within a community of other attendees. The course is delivered through various content types and can be worked through at your own pace.
