The Gas Discharge Tube Arresters (GDT) are an important part of the power line protection system that is designed to protect electronics and communications equipment as well as electrical components from high voltage electrical spikes. GDTs are small, air-filled tubes with special dielectric elements that absorb the electric energy and distribute it safely, reducing its impact on sensitive equipment. GDTs are designed to withstand high voltages with low energy, thus providing a more reliable protection than alternate systems for lightning and other over-voltage protection.

When an over-voltage spike occurs, GDTs provide protection by absorbing the electric energy and dispersing its components in a safe manner. This process begins when the high voltage current travels through the arresters’ specially designed dielectric material, which causes a gas discharge. The electric energy then passes through the dielectric in an arc, which vaporizes the material and dissipates the excess energy. This process prevents most of the energy from passing through to the protected equipment.

2015-50-SMH-RPLF arresters are high performance type 2 surge arresters commonly used in overhead distribution networks and substations. They are engineered to provide supreme surge arrestor performance at all times in a wide range of operating conditions. The 2015-50-SMH-RPLF arrester has a wide range of nominal discharge currents ranging from 20 kA to 100 kA. It is also equipped with a highly protective, polymeric case to ensure safe operation even in the most extreme conditions.

2015-50-SMH-RPLF arresters are designed to respond to a wide range of lightning surge voltages. The voltage limitations are determined by the maximum voltage that an unprotected cable system will withstand when a lightning surge is applied. This voltage is generally twice the normal operating voltage of the power system. The arrester is designed to limit the voltage peak so that it does not exceed the voltage threshold. When the voltage threshold is exceeded, the arrester conductive element responds by providing limiting action to protect the power system.

The 2015-50-SMH arrester is also specifically designed to be highly resistant to environmental influences such as extreme weather, water, dust, moisture and vibration. It utilizes advanced metal oxide varistors to provide superior protection. It is also designed and tested for long life performance with an adjustable end-stage protection feature to adapt for changes in operational environment. This feature allows the user to quickly and easily alter the protection level to suit the application.

2015-50-SMH-RPLF arresters are also designed with special dielectric elements that provide superior insulation resistance and ensure the efficient and reliable operation of the system. The order-to-order silica impregnation process ensures that the protective materials are applied in an optimal field-aligned fashion for long-term performance. Additionally, this process provides improved tracking resistance, providing superior durability in extreme weather conditions.

The 2015-50-SMH-RPLF arrester is the latest in a long line of power line protection products that have been designed by industry professionals to help protect the power system from lightening and other over-voltage situations. Its use of advanced materials and innovative designs ensure reliable performance, minimal wear and maximum safety. This powerful GDT system is an essential component of the current power distribution system and will no doubt be a major player in the future of power line protection.
