Electrical Wire & Cable Specialists

Boat battery cables , like many electrical conductors, are made of copper, but there’s something unique about them that helps protect them from the environments in which they operate. Whether you’ve done your own marine wiring or simply perused marine grade battery cables at an electrical depot, you’ll probably have noticed that they appear silver. They’re not silver, though. In fact, they’re not even aluminum, which appears silver and actually is used to complete electrical wiring in some locations, due to its excellent conductivity, lightweight nature, and ductility. Boat battery cable is, instead, made up of a very large number of individually tinned copper conductors, which gives it this silver appearance. Saltwater and Copper: Not Friends Copper is an excellent conductor because it allows free electrons to passage through the medium at a very low resistance, which means that a little bit of copper can accommodate a fairly high current or voltage wi...

Electrical wire and cable are often qualified according to special traits that make them suitable for their intended applications. For example, marine battery cable is extra flexible and resistant to corrosion. Photovoltaic, or PV cable, must be resistant to the elements and specifically resistant to UV light. Otherwise, they would not be well-designed for their intended purposes. AWG fire alarm cables are no different. Designed to carry low voltage loads and to ensure uninterrupted communication around an alarm circuit, high-quality AWG fire alarm cables , like so many other types of electrical cables, are designed with a number of features that make them suitable for their use in fire alarms systems. Notably, the following three traits guarantee quality. 1. Resistance to high heat; Flame-retardance First, and perhaps most obvious, it is important that fire alarm cables are finished with insulation that is highly resistant to high temperatures. Specifically, it is helpful if the i...
