NLL Series Bolt Type Aluminum Alloy Strain Clamp And Insulation Cover
Designed specifically for overhead lines with voltage ratings of 20 kV and below, the NLL series bolt type aluminum alloy strain clamps effectively secure aluminum stranded wires or steel core aluminum stranded wires onto strain poles. These clamps are particularly beneficial when working with overhead insulated aluminum conductors, offering protective and insulating properties that are essential in power distribution networks.
Features
- The clamp body is constructed from high-strength aluminum alloy, ensuring durability.
- Elegant design catering to both functionality and aesthetics, with a long service life.
- Installation is straightforward, contributing to energy efficiency.
- The product employs a bolt connection system, offering a firm grip with energy-saving accessories that mitigate losses, like hysteresis or eddy currents.
Performance Features of the Insulation Cover
- Withstand voltage capabilities of 1-10kV should be at least 18kV, with no breakdown after one minute of holding voltage.
- 20kV withstand voltage should be at least 30kV, also maintaining integrity with no breakdown after holding voltage for one minute.
- Insulation resistance records at approximately 1.0xΩ.
- Effective operational temperature range is between -30°C and +90°C.
- The insulation cover's climate resistance remains robust after subjected to an artificial climate aging test lasting several hours.

Understanding Strain Clamps
Strain clamps serve the critical role of securing conductors and ground wires to tower arms and substation structures, primarily through the use of insulators or link fittings. They are integral to the effective functioning of transmission and distribution lines.
In summary, the strain clamps are essential for corner, splicing, and terminal connections, bolstering operational integrity and reliability within power line systems. The NLL series not only provides superior gripping force but also facilitates easier installation, leading to reduced operational costs.
