Even electrical experts often mix up professional terms in this industry. Lightning arresters and surge arresters are two easy-to-confuse devices.The difference between surge arrester and lightning arrester Many people think they are the same, but they are not. Workers install…
On September 26, 2024, a group of engineers touched down in Dar es Salaam, Tanzania, ready to upgrade the city’s power grid. For years, Dar es Salaam had frequent blackouts—its old insulation parts just couldn’t handle the harsh weather and…
FRP Crossarms, as a critical infrastructure in power transmission systems, overhead power lines—also referred to as transmission lines or power cables—are composed of suspended cables and wires. Their primary function is to deliver electricity safely and efficiently between multiple locations,…
Distribution Systems: In low-voltage distribution lines of power transmission systems, FRP crossarms function like human shoulders—resisting not only the weight of conductors but also harsh environmental conditions such as strong winds, ice accumulation, and accidental impacts. Having replaced the traditional…
Tanzania started its rural electrification plan. The old 11kV power lines used traditional ceramic insulators, which broke easily, got dirty quickly and cost a lot to maintain. Our team decided to use composite post insulators to upgrade these lines. These…
The crossarm is an important component of pole and tower. It is used to install insulators and hardware fittings, support conductors and lightning wires, and maintain a specified safe distance for them. 1. Functions of Crossarm The crossarm refers to…
With the development of the power industry, ceramic and polymer insulators are often among the key components in power transmission networks, serving as critical points that directly impact system reliability and grid transmission safety. 1. Ceramic Insulators 1.1 Definition and…
