LoviSil®
Oil Refill Sleeves

LoviSil® oil refill sleeves prevent the drying out of GLCC 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 GPLK is coupled with modern XLPE cables. A robust, sustainable solution that keeps networks reliable during renovation and transition.

  • Lifetime extension of GPLK networks – keeps paper-insulated cables in optimal condition, even during network expansions.

  • Prevents paper insulation from drying out – continuous oil management protects fragile GPLK conductors from aging.

  • Widely applicable – suitable for medium voltage (12, 24 and 36 kV) and can be used in a wide range of grid configurations.

Well thought-out cable sleeve construction – a plastic oil saddle and pipe create a safe oil supply to the cable sheath.

Reliable connection – robust outer shell and durable couplings ensure a long-term stable oil level.

Flexible integration – easy to connect to different oil reservoirs to suit various grid configurations

Compatible with multiple cable types – can be used with medium-voltage GPLK cables and, for example, GPLK with H-foil.

Applications

LoviSil® oil refill sleeves are ideal for medium-voltage grids in the energy sector and industry, such as theelectrochemical and pharmaceutical industries. They retain existing b 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
