Tinned Brass Line Taps Split Bolt Connectors

Tinned Brass Line Taps – Split Bolt Connectors

Tinned Brass Line Taps (Split Bolt Connectors) are high-conductivity electrical connectors used for joining, tapping, and branching conductors in power distribution and grounding systems. We are one of the leading manufacturers and exporters of Tinned Brass Line Taps from India. We have been supplying Brass Electrical Connectors and Split Bolt Connectors to the world market for many decades. Manufactured using high-grade Brass and electro-tinned for superior corrosion resistance, our Split Bolt Line Taps provide strong mechanical grip, low contact resistance, and long service life in demanding industrial environments. These connectors are widely used in Overhead Line Installations, Earthing Systems, Transformer Yards, Distribution Networks, and Industrial Electrical Projects worldwide.

Overview – Tinned Brass Split Bolt Connectors

Tinned Brass Line Taps, commonly known as Split Bolt Connectors, are designed to join Copper or Aluminium conductors securely. The split bolt mechanism allows multiple conductors to be clamped together with high mechanical strength and excellent electrical conductivity.

Key Functional Benefits:

  • High electrical conductivity

  • Strong mechanical clamping force

  • Corrosion-resistant tinned surface

  • Suitable for grounding and line tapping

  • Reusable and easy to install

  • Compatible with Copper conductors

The electro-tinned coating enhances oxidation resistance and improves long-term performance in outdoor and high-humidity environments.

Material Grades & International Standards

Our Tinned Brass Line Taps are manufactured using premium-grade Brass and conform to international quality standards.

Physical & Electrical Properties

Property Typical Value
Electrical Conductivity Excellent
Tensile Strength 300–550 MPa
Corrosion Resistance High (Tinned Surface)
Operating Temperature -20°C to +150°C
Contact Resistance Low
Plating Thickness 8–15 Microns (Tin)

The Tin plating enhances conductivity at contact surfaces and prevents surface oxidation.

Construction & Working Principle

The Split Bolt Connector consists of:

  1. Brass Body (Split Thread Design)

  2. Threaded Bolt

  3. Hex Head for Tightening
