Heat always flows from a hotter object to a colder one.
So: Heat 'transfers' from 'hot' to 'cold' (cold being a relative term and considered an absence of heat).
Heat transfer can be unidirectional (one-way transfer of heat from one object to another), such as in conduction or convection, or bidirectional (two-way transfer of heat between two objects), such as in radiation. The direction of heat transfer depends on the temperature difference between the objects involved and the properties of the materials.
The only way to transfer heat in a vacuum is through radiation. Heat transfer by convection and conduction require a medium, such as air or a solid, to transfer energy. In a vacuum, radiation is the only method by which heat can move.
Insulation is not a method of heat transfer, but rather a way to slow down the transfer of heat between objects by using materials that have low thermal conductivity. Heat transfer occurs through conduction, convection, and radiation, where heat moves from a warmer object to a cooler one.
It's a different way to transfer heat. One object emits electromagnetic radiation (for example, infrared - though it depends on the temperature); another object absorbs it. Heat transfer through radiation can occur in empty space; with conduction and convection, that's not possible.
The movement of heat by way of fluid is called convection. It involves the transfer of heat through the motion of the fluid particles.

in power lines, the best way to eliminate heat transfer is to transport energy with a high voltage and low current.
The main way of heat transfer is conduction. Mostly in the cases of solids , so by preventing contact , heat transfer can be hampered.

They both are the way or the process to transfer heat.
Convection Currents
yes convection is way of heat transfer. example : in boilers evaporators are heated up with exhaust gases of coal burning., smoking cigareetes have convective heat transfer to mouth.

Heat is primarily transferred through conduction, convection, and radiation. Conduction is the transfer of heat through direct contact of materials, convection is the transfer of heat through the movement of fluids, and radiation is the transfer of heat through electromagnetic waves.
