To decide between an underground and overhead power cable system selection, first, you need to know how these cable systems operate and what their benefits and drawbacks are.
Underground Power Cable System
An underground power cable passes under the ground and connected to the property’s meter box and the power received from the street’s network. For new suburbs and some areas in Sydney’s CBD, an underground electrical system is obligatory. Like overhead, underground power cable system comes in single and three-phase options.
Do you think you want to make a shift from overhead power cable lines to underground power cable lines? Well, you need to take the help of a level 2 electrical contractors, who can evaluate your circumstances and accordingly, offer you with the best-suited recommendation.
Benefits of Underground Power Cable System
- Cabling is secured, power lines are safe within the electrical piping passage.
- It needs minimal maintenance.
- Power lines do not inflict any threat to trucks, wildlife and other likely contact crashes.
- Avert illegal connections.
- It is less vulnerable to atmospheric elements.
- Appropriate for highly populated areas.
Drawbacks of Underground Power Cable System
- Any damages to the cabling can’t be spotted.
- If any metal corrosion occurs on electrical pipes, then it can be an element that leads to power line interruption.
- It needs little maintenance; however, when damages are detected, repairing costs are higher.
- Installation costs are dearer. Electrical passage cost more particularly if it’s of high-quality and sturdy.
Overhead Power Cable System
An overhead power cable contains conductors that facilitate electrical flow. Supported by poles, an overhead power cable can transmit electrical energy for long distances. You will most probably see an overhead power cable when you step into your front yard. They pass from the street’s network pole to the property or a private power pole. Typically, overhead power cable range from 100amps to 400amps service, and depending on the property’s requirements, an overhead power cable come in single or three-phase.
For instance, a home requiring basic electricity to run electrical appliances such as television and lighting will need a single-phase supply. Conversely, a house equipped with advanced and more number of electrical appliances — for instance, three air conditioners, one or two refrigerators, microwave, television, computer, lighting and other electrical devices will require a three-phase supply line. Also, a warehouse that powers large industrial equipment would require a three-phase supply line. If a property has more electricity intake, it’s only prudent to set up a three-phase power supply line to avoid overloading issues.
