The Science of Heat Transfer: What Is Conduction?

Heat is an interesting form of energy. Not only does it sustain life, make us comfortable and help us prepare our food, but understanding its properties is key to many fields of scientific research. For example, knowing how heat is transferred and the degree to which different materials can exchange thermal energy governs everything from building heaters and understanding seasonal change to sending ships into space.

Heat can only be transferred through three means: conduction, convection and radiation. Of these, conduction is perhaps the most common, and occurs regularly in nature. In short, it is the transfer of heat through physical contact. It occurs when you press your hand onto a window pane, when you place a pot of water on an active element, and when you place an iron in the fire.

Aerial Bundle Cables, often referred to as Aerial Bundled Conductors or simply ABC, are cables for overhead line power, so called for combining multiple single core cables together. With applications including temporary power distribution to street lighting and secondary pole-to-pole service cables, they are lightweight stranded aluminium conductors, both single core and multi-cores. Whilst Aerial Bundle Cables are used in rural power distribution in some countries, they are more commonly used in temporary power installations such as on construction sites. As insulated cables they are often preferred to bare conductors which are installed and separated by air gaps but where sparks and shorts in the event of high winds may cause resulting bushfires in dry climates or risk nearby property. The XLPE insulation material, and where relevant the sheathing material, allows the ABC to be tightly bundled together – additional steel wire supports similar to those in ACSR can also be incorporated as catenary wires .

What Types of Wire Are Used on Solar Farms?

Solar power installations in the US have grown 35 fold since 2008, while the average cost of photovoltaic panels has dropped 50% since 2014. Over 242,000 people work in the solar power industry in the US, which is more than double the number in 2012.

Fiber Optic Cable

Fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves.
