LV Insulated Piercing Connectors By Pfisterer
Low Voltage Live Working (1kV) & Cable Jointing
Live line working is increasingly essential in low voltage networks. Ensuring safe live line working is imperative even at low voltages. Bolted connectors used for this purpose should be easy to install and ensure the best possible occupational safety.
The LV insulated piercing connector family from PFISTERER has been developed to meet today’s practical requirements.
Durable contacts come as standard, and have been a PFISTERER core competence for nearly 100 years.

Insulated Piercing Connectors LV
Benefits
- Increased occupational safety
- IP2X / creepage distance
- Ideal for live line working (AuS)
- Quick and simple Installation
- No stripping of conductors required
- Shear-off bolts prevent installation mistakes
- Reliable design – electrical & mechanical qualified according to IEC 61238-1 class A
- Compact dimensions – less cast resin when jointing cables
- Applicable with resin and heat shrink sleeves
Cover caps with “spiral spring”
- Touch-safe during all installation steps
Insulation body
- IP2X protection against finger contact
SICON Technology
- Stepless shear bolt: Full utilisation of the thread loading ensures optimum contact forces
Inspection hole
- Easily check the position of the conductor in the connector
Plastic flaps
- Protection against accidental contact
Insulating barrier
- Extends the creepage distance
Elastomer inlay
- Protects against contact after the bolts sheared off
Piercing technology
- Rotatable friction disc pierces the insulation: Makes reliable contact trough the conductor insulation on paper and plastic insulated cables
Tin-plated connector body
- Prevents the formation of an oxidation layer
Advantage of the patented, movebale friction disc
