100A Copper Contact Grounding Block with 50mm Bottom Diameter for Temporary Line Grounding

100A Copper Grounding Block for Temporary Line Grounding

Before a crew touches a conductor that could be energised by induction or backfeed, it has to be grounded. This grounding block clamps the conductor or steel rope and connects it to the grounding system, giving fault and induced current a defined path to earth during stringing and maintenance.

Design Features and Field Benefits

• Copper Contact for Low Resistance: Copper contact components give a low resistance joint at the conductor, which is the point where a poor connection would create heat and voltage drop.
• Cast Steel Body Withstands Site Abuse: The cast steel clamp body resists deformation when tightened and survives being dropped, dragged and stored in a tool truck.
• Fits Conductor and Steel Rope: A 50mm bottom opening accepts 38-48mm conductors, steel wire rope and grounding wire, so one block covers several grounding tasks.
• Clear 100A Rating: The 100A maximum current is stated on the unit and in the datasheet, so supervisors can verify it against the grounding study.

Grounding block specification

Dimensions and ratings are nominal. Confirm the exact model against the datasheet before ordering.

Product Overview

The contact components are copper and the body is cast steel, a combination chosen for conductivity at the contact face and mechanical strength in the clamp. The 50mm bottom diameter suits a 40mm conductor as well as steel wire rope and grounding wire, and the 100A maximum current rating covers temporary grounding on transmission and distribution construction work.

Typical Applications

• Temporary grounding during stringing
• Transmission line construction
• Distribution maintenance
• Steel wire rope grounding

Selection Guidance

• Confirm the conductor or rope diameter fits the 50mm opening before use.
• Check the grounding study against the 100A maximum current rating.
• Inspect the copper contact faces for corrosion before each use and clean them if necessary.

Quality Control and Delivery

Units are assembled in an ISO 9001 certified workshop. Frames are checked for sheave alignment and axle straightness, load bearing parts are inspected before assembly, and finished units are function checked before packing. Export packing is a plywood case with a moisture barrier, and a 12 month warranty covers manufacturing defects. Inspection records and, on request, third party load test certificates can be supplied with the shipment.
