Quality Inspection for 300kn Porcelain Insulator - Hot dip galvanized steel Electric Power Fitting – Johnson

Products Information

1. Different applicable places

1. Nll-2 strain clamp: applicable to 10kV and below overhead lines.

2. Nld-2 strain clamp: used for corner, connection and terminal connection. Spiral aluminum clad steel wire has very strong tensile strength and no concentrated stress, which plays a role in protecting and assisting vibration reduction of optical cable.

2. Different functions

1. Nll-2 tension clamp: fix aluminum stranded wire or steel core aluminum stranded wire on the tension rod. When it is used for overhead insulated aluminum conductor, it is used together with the insulating cover for insulation protection.

2. Nld-2 tension clamp: it is used to fix the conductor or lightning wire on the tension insulator string of non-linear pole and tower for anchoring. It is also used to fix the stay wire of stay wire pole and tower.

3. Different characteristics

1. Nll-2 strain clamp: the clamp body is made of high-strength aluminum alloy, with smooth appearance, long service life, convenient installation and use and no power loss. It is an energy-saving certified product.

2. Nld-2 tension clamp: Tension pre twisted wire and supporting connecting fittings. The grip strength of the clamp shall not be less than 95% of the rated tensile strength of the optical cable, which is convenient and fast to install and reduces the construction cost. It is applicable to ADSS optical cable lines with span ≤ 100m and line angle < 25 °.”
