High voltage cable testing will maximize the dependability of motors, generators, and transformers. Routinely testing your cables is important because testing will determine if there are any existing issues. Potential problems can cause damage over time and may eventually cause your cables to fail. These problems may result from defects in installation or a mis-wire. Although low voltage testing can determine if there is a dead short in the wires, high voltage cable testing is necessary when wires are not physically touching. By ensuring proper high voltage installation, an electrical contractor will minimize the risk of potential high voltage problems.
Horizontal Directional Drilling & Trenching
Horizontal directional drilling is also referred to as directional boring. Horizontal directional drilling, or HDD, is a steerable trenchless method of installing underground pipes, cables, and conduits in a small arc following a given bore path. This is done by using a surface launched drilling rig, which leaves minimal impact on the adjacent areas. There are several benefits of HDD, including low cost and low impact on the environment. An electrical contractor can cater to your drilling needs and utilize horizontal directional drilling when necessary.
Cable Laying, Jointing, & Testing
Cable laying services install fiber optic cable or copper cable in different structures or over large distances. Cable laying can involve low voltage, medium voltage, and/or high voltage lines. It is essential that all high voltage and medium voltage cable installations are performed under the required standards and according to each individual manufacturer's recommendations. Horizontal directional drilling equipment is often used for underground cable laying services. An experienced electrical contractor will ensure proper cable laying procedures and perform the appropriate tests to determine any potential problems.
Fault Finding Services
An electrical fault is any abnormal flow of electric current. For example, a fault in which current flow exceeds the normal load is called a short circuit. There are several different types of electrical faults including transient, persistent, symmetric, and asymmetric faults. Electrical contractors provide sheath fault locating and high voltage cable fault finding by utilizing fault finding equipment such as thumper and burndown units. A thumper test set provides a high-energy, high-voltage pulse to the cable.
An electrical contractor can provide proper electrical installation and perform tests to determine any potential problems. Through services such as high voltage installation and testing, horizontal directional drilling and trenching, cable laying, jointing, and testing, and fault finding services, electrical contractors maximize the effectiveness and safety of your electrical equipment.
