Reasons Surge Voltage Limiters (SVL) in Link Boxes Are Essential for Power Safety

When it comes to electrical safety, surge protection is crucial. A sheath voltage limiter (SVL), is an arrester that reduces the risk of damage to cable insulation by limiting overvoltage levels on cable sheaths during a short circuit or surge spikes event.

Link Box with SVL

A link box is a unit in which bonding or grounding connections are made through removable links, and also contain arrestors functioning as sheath voltage limiters (SVLs), depending on the bonding requirements. By integrating an SVL into a link box, you’re effectively protecting the entire electrical circuit downstream.

Reasons Why SVL in Link Boxes is essential:

Prevents Equipment Damage: The most obvious benefit of using an SVL in a link box is preventing costly power cables damage. SVLs prevent the cable jacket or link box from breaking down due to insulation, limit the voltage stress across the cable jacket, protect the screen separation of power cable joints from damage caused by short circuits or breakdowns, protect against high voltage surges that can occur from lighting or switching transients, or short-circuit currents. 

Reduces Downtime: Power transmission failure due to surges can lead to significant downtime. This can disrupt productivity, transmission, cause financial losses, and inconvenience to users. With an SVL in place, you can minimize downtime.

Enhances Safety: Surges can pose a safety hazard. An SVL helps to mitigate the risk of electrical fires and shocks by preventing excessive currents from flowing through the circuit.
