Product Specification Sheet

Product Introduction

Parallel Groove Connector AL is mainly used for transmitting current between the interconnected conductors, for example for connection loops on terminal poles or tapping off bus-bars to equipment on substations.

Special designed screw hole and arc shape of the body allow clamp to adjusts to different cable size on each side; Materials of bolt and nut are optional depend on customer request. Options including Hot-dip galvanized steel and Stainless steel ; Pressure pad is applied to achieve uniform pressure along the clamp.

Our design fulfills also the following important criteria:

Holding strength: An adequate mechanical holding strength is achieved. In case of higher values two or more PG-clamps should be used in series.

Corrosion resistance: Maximum corrosion resistance is achieved by using a clamp material that matches with that of the conductor, for example a corrosion-resistant AlMgSi alloy for conductors made of aluminium, al-alloy etc.

Gross-grooved clamp channels enhance both mechanical pullout strength and electrical conductivity.

The installation and use is simple, wire-clamps strength is high, without any magnetic hysteresis.

Installation Method

1.Before connector installation, it is recommended to clean the conductors with steel brush of dirtiness and/or dust
2.Unscrew bolt of PG connector to have enough space to place conductors into clamp.
3.Place the conductors (branch and main) in the parallel grooves of the connector as shown on the picture.
4.Screw the bolt of PG connector with adequate wrench till rated torque value which is designated on the PG connector.
