Fully-insulated grounding device is mainly suitable for power inspection and ground connection in overhead insulated electrical construction lines of 1kKV and below. Because it is designed with a closeable electric inspection grounding pole, it is safer than the traditional electric inspection grounding device.

This grounding ring can be effectively used with connection fittings such as special-shaped parallel groove clamps, CHINET clamps, and insulation puncture clamps to form various combined grounding devices, which have the advantages of superior performance, convenient installation, beautiful lines, and maintenance-free. It is our patented product.

a.The grounding aluminum rod is made of high-strength aluminum alloy as a whole, and its surface is profiled. It has high strength and corrosion resistance.

b.The surface part of the ground rod is made of high-quality silicon rubber sealant, which has the advantages of good anti-aging performance and superior insulation performance;

c.The lower end of the grounding cotton is designed with a movable insulation sleeve, which is pulled out when the power is grounded and the exposed part of the power pole is usually closed to make the line safer and more beautiful

d.The grounding rod is provided with a hanging type and a side hanging type, which can meet the different requirements of horizontal overhead lines and vertical down-conductors.
