                           information on how to select a transmission line arrester.

Underbuilt Line Arrester
ArresterFacts 022 - Underbuilt Line Arrester

An arrester in a shielded housing intended to be installed in an enclosure for the protection of underground and pad-mounted distribution equipment and circuits.

Deadfront Arrester
ArresterFacts 025 - Deadfront and Separable Arresters

This arrester type is used to protect cable in residential and industrial underground circuits.

Sheath Voltage Limiter
ArresterFacts 032 - Sheath Voltage Limiter

The main purpose of the sheath voltage limiter is to protect the outer jacket of the cable from electrical stresses caused during transient events.

Gapped MOV Arresters Understanding Gapped MOV Arrester Technology
ArresterFacts 044 - Gapped MOV Technology

The internally gapped arrester utilizes both the gap and MOV disk which work in conjunction to provide better clamping voltage and higher system withstand voltage.
