The stability and safety of power lines are crucial to our daily lives. Reliable power transmission depends not only on the safe operation of cables, but also the effective collaboration of the teams that support these cables. Between these, electrical cable terminations play a fundamental role.
Cable Accessories
Cable accessories are key elements in the installation and maintenance of cable systems. These accessories are used to connect, finish, Protect and isolate cables, which guarantees optimal performance and a greater useful life of the system.
Among the most common accessories are connectors, The terminals, The junction boxes, The protection cases, The thermoretractile tubes and electric insulators. The connectors and terminals are used to join two or more cables and guarantee a safe and stable connection, while junction boxes They are used to join cables of different sizes or types.
Cable accessories are used in a variety of applications. ZMS provides detailed technical information about accessories, as well as instructions for use. Be sure to select the appropriate accessories for each application in order to guarantee optimal performance of your cable system.
What is Electrical Insulator? Types of Insulators
An electrical insulator is an electrical device that insulates conductors from each other and from the conductor to ground.. Ensure that overhead cables have reliable electrical insulation resistance. They are used to hold overhead conductors in place and support vertical and horizontal loads..
How To Judge The Quality Of Cable Accessories?
Cable accessories have an important influence on its use. The factors to judge the quality of the accessories are multiple. In principle, include the following.
Protection Measures Against Lightning in Aerial Cables
as a natural phenomenon, lightning is generated for various reasons. During the frequent annual lightning season, power lines can be significantly affected.
Las 10KV overhead lines are subject to direct and induced lightning, that can generate very high voltages and cause surges in overhead cables.
The lightning surge is usually much higher than the allowable voltage of the line. The lack of protection measures against lightning can easily cause it to strike the insulation., which can lead to fractures at weak points. Serious damage to electrical equipment leads to unnecessary safety accidents.
Post Insulators and Suspension Insulators
insulating post: is a special cable insulation control, an electrical material, which can play an important role in the overhead cables of transmission.
In the first days, post insulators were used primarily for electrical poles.
They gradually developed from the end of high-type high-voltage electrical cable connection towers with many suspended insulators., which were usually made of silica gel or ceramic to increase creepage distance. They are called insulators..
