China OEM Ttd Series Puncture Clamps CZPT shaft collar

Product Description

Product introduction:

The insulation piercing clamp is applicable to the new cable T-connection products of small capacity power and

lighting power supply systems. The use of puncture clamp is another cable T-connection mode after the cable

distribution box and pre branch cable. It has the characteristics of more safe and reliable power distribution,

simple installation, waterproof, low environmental requirements, maintenance free, and more economical. It

can be used in low voltage power and lighting distribution lines such as high-rise buildings, civil residences,

street lamp power distribution, outdoor overhead lines, etc. It can be installed in shafts and outdoors.

Structure composition and type selection

The puncture clamp is connected by a screw with a torque screw through 2 insulation supports separated up

and down. Two pieces of conductors made of special alloy that can contact the conductor at multiple points are

hidden in the insulation support. The puncture clamp is equipped with torque nut and puncture structure. The

torque nut is used to ensure constant contact pressure, ensure good electrical contact, and together with the

puncture structure, make the installation simple and reliable. During installation, it is only necessary to visually

check whether the torque nut is broken, and whether the wire position is appropriate to ensure reliable quality.

After testing, the contact resistance and line insulation resistance meet the requirements of the construction specifications,
and the temperature rise at the joint part of the loaded power on test run is normal The use of

the puncture clamp has little impact on the mechanical and electrical properties of the trunk line.
Now the puncture clamp has a complete range of models, which can easily meet the T-connection needs of the trunk

line of ordinary power lines.

What are the steps for replacing existing fastening methods with shaft clamps?

If you are considering replacing existing fastening methods with shaft clamps, here’s a detailed explanation of the steps involved:

  1. Evaluation and Planning: Start by evaluating the existing fastening methods and assessing the suitability of shaft clamps for your specific application. Identify the reasons for replacing the current fastening method and determine the desired outcomes and performance improvements. Plan the transition process, considering factors such as the number of clamps required, their specifications, and any modifications needed.
  2. Shaft Preparation: Prepare the shaft by cleaning it thoroughly and ensuring it is free from dirt, debris, and any existing fasteners or fastening elements. If necessary, remove any existing fasteners or components that will be replaced by the shaft clamps.
  3. Selection of Shaft Clamps: Choose the appropriate shaft clamps based on the requirements of your application. Consider factors such as shaft diameter, material compatibility, load capacity, and any specific features needed for your application (e.g., high-speed rating, corrosion resistance, etc.). Refer to the manufacturer’s specifications and guidelines to ensure proper selection.
  4. Positioning and Alignment: Position the shaft clamps at the desired locations along the shaft. Ensure proper alignment and concentricity with the shaft and the components being fastened. Use alignment tools or precision measurement instruments as needed to achieve accurate positioning.
  5. Installation: Install the shaft clamps by following the manufacturer’s instructions. Typically, this involves tightening the clamping screws or bolts evenly and gradually, ensuring that the clamps apply sufficient clamping force without causing deformation or damage to the shaft or components. Use the recommended torque values and tightening sequence provided by the manufacturer.
  6. Testing and Adjustment: After installing the shaft clamps, conduct thorough testing to ensure proper fastening, alignment, and performance. Check for any excessive vibrations, slippage, or misalignment. Make adjustments as necessary, such as tightening or loosening the clamps, repositioning components, or adding additional clamps for improved stability.
  7. Monitoring and Maintenance: Regularly monitor the performance of the shaft clamps and the overall system. Inspect the clamps for any signs of wear, looseness, or corrosion. Follow the manufacturer’s recommendations for maintenance, such as periodic inspection, lubrication, or replacement of components.

It’s important to note that the steps for replacing existing fastening methods with shaft clamps may vary depending on the specific application, machinery, and manufacturer recommendations. It’s advisable to refer to the manufacturer’s documentation, consult with qualified engineers or technicians, and follow industry best practices to ensure a successful transition and optimal performance with shaft clamps.
