Crimp Force Requirements
Crimp force is a crucial factor in ensuring the reliability and performance of Burndy crimps. Using the correct crimp force ensures proper contact between the wire and the terminal, resulting in a secure and durable connection.
The recommended crimp force values vary depending on the wire size and crimp type. The following table provides guidelines for the appropriate crimp force for different combinations:
Recommended Crimp Force Values, Burndy crimp chart
| Wire Size (AWG) | Crimp Type | Crimp Force (lbs) |
|---|---|---|
| 22-16 | Standard | 150-250 |
| 14-10 | Standard | 250-350 |
| 8-6 | Standard | 350-450 |
| 4-2 | Standard | 450-550 |
| 1/0-4/0 | Standard | 550-650 |
| 250 kcmil-500 kcmil | Standard | 650-750 |
| 750 kcmil-1000 kcmil | Standard | 750-850 |
It is important to use a calibrated crimping tool to ensure accurate crimp force application. Proper crimping practices, including the use of the correct crimp die and maintaining the crimping tool, are essential for achieving reliable and consistent crimps.
Crimp Height Specifications: Burndy Crimp Chart
Maintaining proper crimp height is crucial for ensuring a reliable electrical connection. Incorrect crimp height can result in loose connections, increased resistance, and potential failure. Therefore, it is essential to adhere to the specified crimp height values for Burndy connectors.
The table below provides crimp height specifications for various Burndy connectors. These values are measured from the bottom of the connector barrel to the top of the crimp.
Crimp Height Specifications for Burndy Connectors
| Connector Type | Crimp Height (in) |
|---|---|
| YA Series | 0.215 ± 0.005 |
| Y Series | 0.235 ± 0.005 |
| RT Series | 0.255 ± 0.005 |
| PY Series | 0.275 ± 0.005 |
| P Series | 0.295 ± 0.005 |
To ensure accurate crimp height, a crimp height gauge should be used. This tool measures the distance between the bottom of the connector barrel and the top of the crimp. By comparing the measured crimp height to the specified values, you can verify that the crimp meets the required standards.
Wire Stripping Lengths
Determining the correct wire stripping lengths is crucial for ensuring the integrity and performance of Burndy crimps. Improper stripping lengths can compromise the electrical connection and increase the risk of failure.
The recommended wire stripping lengths vary depending on the wire size and crimp type. The following table provides guidelines for optimal stripping lengths:
Wire Stripping Lengths Table
| Wire Size (AWG) | Butt Splice Crimp | Ring Terminal Crimp |
|---|---|---|
| 12 | 3/8" - 1/2" | 5/8" - 3/4" |
| 14 | 3/8" - 1/2" | 5/8" - 3/4" |
| 16 | 1/4" - 3/8" | 1/2" - 5/8" |
| 18 | 1/4" - 3/8" | 1/2" - 5/8" |
| 20 | 1/4" - 3/8" | 1/2" - 5/8" |
| 22 | 1/8" - 1/4" | 3/8" - 1/2" |
| 24 | 1/8" - 1/4" | 3/8" - 1/2" |
Consequences of Incorrect Wire Stripping Lengths
- Insufficient Stripping Length: Too little stripping can result in poor electrical contact, leading to increased resistance, overheating, and potential failure.
- Excessive Stripping Length: Stripping too much wire can weaken the crimp and reduce its tensile strength, making it more susceptible to breakage.

Crimp Quality Inspection
Ensuring the quality of crimped connections is crucial for maintaining safety and reliability in electrical systems. Regular inspections are essential to identify and rectify any potential issues that may compromise the integrity of the connections.
Visual Inspection
Visual inspection involves examining the physical characteristics of the crimp connection. This includes:
- Uniformity: The crimp should be evenly distributed around the wire, without any gaps or overlaps.
- Alignment: The wire and terminal should be properly aligned within the crimp.
- No Burrs or Nicks: The crimp should be free of any burrs or nicks that could damage the wire or terminal.
- Proper Insulation Crimp: The insulation crimp should provide adequate protection for the wire.
Electrical Inspection
Electrical inspection involves testing the electrical continuity and resistance of the crimp connection. This can be done using:
- Continuity Test: A continuity test verifies that the wire and terminal are electrically connected.
- Resistance Measurement: Measuring the resistance across the crimp connection ensures that there is no excessive resistance that could affect current flow.
Importance of Regular Inspections
Regular crimp inspections are essential for several reasons:
- Safety: Poor crimp connections can lead to overheating, sparking, and electrical fires.
- Reliability: Loose or damaged crimps can cause intermittent connections, equipment malfunctions, and data loss.
- Compliance: Many industries have specific regulations regarding the inspection and maintenance of crimp connections.
By conducting regular crimp inspections, organizations can proactively identify and address potential issues, ensuring the safety, reliability, and compliance of their electrical systems.
