LoviSil®
Oil Refill Joints
Avoid costly cable replacement with smart oil refill solutions
Prevent drying out, avoid failures and delay costly replacement
Problem
Aging PILC cables depend on a continuous oil supply to maintain their insulation performance
When networks are modified or upgraded, this oil supply is often interrupted, leading to drying out of the cable insulation and increased risk of failure
Solution
LoviSil oil refill joints restore and maintain the oil supply in existing cables
This prevents insulation degradation, ensures reliable operation and allows existing assets to remain in service for longer
LoviSil® oil refill joints prevent the drying out of PILC cables and thus extend the life of existing medium-voltage networks. Thanks to a well-thought-out construction, the oil supply is maintained even when PILC is coupled with modern XLPE cables. A robust, sustainable solution that keeps networks reliable during renovation and transition.
Applications
LoviSil® oil refill joints are ideal for medium-voltage grids in the energy sector and industry, such as the petrochemical and pharmaceutical industries. They retain existing PILC networks and allow a secure connection with new XLPE cables. The joint supports reliable renovations and extends the lifespan of existing assets. This keeps the grid performing stably, even under harsh conditions
- Extend the lifetime of existing cable assets
- Avoid costly cable replacement projects
- Enable safe transition from PILC to XLPE cables
- Maintain network reliability during renovation and upgrades
Where
Network renovation projects where existing cables need to be preserved
Transitions from PILC to modern XLPE cable systems
Industrial environments such as petrochemical and pharmaceutical facilities
The oil refill joint integrates a dedicated oil supply system that connects the cable to an external reservoir
This ensures continuous oil saturation of the paper insulation, preventing drying and maintaining dielectric performance
