Link Box with SVL & without SVL – Detailed Description
Link Box (Link Box with SVL & without SVL) is an essential component used in underground and high-voltage cable systems for effective bonding, grounding, and protection of cable sheaths. It is primarily designed to manage induced voltages in cable screens and ensure safety, reliability, and long service life of power transmission networks.
A Link Box with SVL (Sheath Voltage Limiter) includes surge protection devices that safeguard the cable sheath insulation from overvoltages caused by lightning strikes, switching surges, or fault conditions. The SVL limits transient voltages and prevents damage to the cable system, ensuring continuous and safe operation.
On the other hand, a Link Box without SVL is used in standard bonding applications where overvoltage protection is not required. It provides reliable earthing and bonding of cable sheaths, helping to reduce circulating currents and maintain system stability.
These link boxes are manufactured using robust, weather-resistant enclosures (such as stainless steel or polymer), making them suitable for both indoor and outdoor installations. They are designed for easy access, secure connections, and long-term durability under harsh environmental conditions.
