HV Terminations

TE Connectivity’s (TE) Raychem High Voltage Outdoor Termination (OHVT) Dry Type is designed for voltages up to 245 kV and to operate under severe environmental conditions. The OHVT is compatible with polymeric insulated cables independent of the manufacturer and can be adapted with respect to grounding required for various cable constructions.

Composite housing with different creepage lengths are available and cover all pollution levels. The installation of the termination can be done by trained installer equipped with conventional tools. The termination is designed according to the following standards: IEC-60840, IEC-62067, IEC-60815, IEEE-48, IEEE-1313.

The pressure-tight composite housing is made of a glass fiber reinforced (GFR) resin tube with silicone rubber sheds molded to the tube. The metal fitted associated with the termination consists of a corrosion-free alloy. The cable lug is available both in crimp and shear-off bolt version. It is suitable for all common conductors made of aluminium or copper. The interface between stress cone, cable insulation and inner housing will be filled from the top with fast curing gel. The advantage of a dry type termination over a conventional oil filled type is that the gel filling cures over a time period causing no leakages.
