How to assemble a reliable extension cord for winter so that the wire does not harden

Self-assembly of the extension cord is required when there is an urgent need for its use. This can be either unplanned repair work or a situation where a factory product is not able to withstand the load of an electrical device. Often, in the factory manufacture of extension cords, significant savings are made precisely on the cable section, which becomes the cause of all the ensuing problems during use. To exclude any consequences from a poor-quality device, it is recommended to independently assemble an extension cord that meets all the necessary parameters.

Before starting work, you must first collect all the constituent elements:

1. Electric plug - you can buy a new one or remove it from an old unused or failed device. A prerequisite is the presence of grounding in it.
2. Three-core cable of appropriate length. This element needs to be given special attention, since not every PVC coating is designed to work in winter conditions. Many modern cable manufacturers position their coating as resistant to frost and ultraviolet. However, it is better to play it safe and use a corrugated pipe to protect PVC. An alternative would be to use a cable whose insulation is made of polyethylene. This material is characterized by its ability to maintain elasticity at temperatures up to - 50 degrees Celsius. Section calculation is based on the planned load.

3. Socket or block. Without fail, the device must be equipped with grounding and a closed rear wall. In order to use the assembled device in the winter season, it is recommended to make its body dustproof and waterproof.

Of the necessary tools for work, you will need: a multimeter, two types of screwdrivers, a knife, electrical tape and pliers.

After all the materials and tools are collected, you can safely get to work.

In conclusion, I would like to add that equipping the device with an additional switch in the form of a button can significantly increase its level of security.

The process of self-assembly of the extension cord does not require deep knowledge in working with electrical devices. It is important to select high-quality materials, as well as to pay due attention to the assembly of each element. Additional equipment with frost-resistant materials will make it possible to assemble the device more functional and reliable than the option purchased in the store.
