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
Los accesorios de cables son elementos clave en la instalación y mantenimiento de sistemas de cables. Estos accesorios se utilizan para conectar, terminar, proteger y aislar los cables, lo que garantiza un rendimiento óptimo y una mayor vida útil del sistema.
Entre los accesorios más comunes se encuentran los conectores, las terminales, las cajas de empalme, las fundas de protección, los tubos termorretráctiles y los aislantes eléctricos. Los conectores y terminales se utilizan para unir dos o más cables y garantizar una conexión segura y estable, mientras que las cajas de empalme se utilizan para unir cables de diferentes tamaños o tipos.
Los accesorios para cables se utilizan en una variedad de aplicaciones. ZMS proporciona información técnica detallada sobre los accesorios, así como instrucciones para su uso. Asegúrese de seleccionar los accesorios adecuados para cada aplicación a fin de garantizar un rendimiento óptimo de su sistema de cables.
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..
