本产品适用于高压单芯电力电缆金属护套的直接接地。采用不锈钢作为保护外壳，内部可浇注树脂，集不可拆、全密封、防盗性的特点于一身。有体积小、重量轻、安装方便快捷的诸多优点。

This product is suitable for direct grounding of the metallic sheath of high-voltage single-core power cables. It uses stainless steel as the protective shell, and the interior can be filled with cast resin, combining the features of being non-removable, fully sealed, and theft-proof. It has many advantages such as small size, light weight, and convenient and quick installation.

1DC withstand voltage test / 20kV, duration 1 min, no flashover, no breakdown

2Impulse voltage test / peak 40kV, 10 times each of positive and negative polarity, no flashover, no breakdown

3Insulation resistance test between connecting busbar and enclosure / not less than 20MΩ

4Contact resistance test of connecting busbar / not greater than 20μΩ
