二、 Structural Characteristics
1.This tester is a monolithic structure, composed of bending welded steel plate and the exterior been protectively painted.
2.The tester input voltage of 220V, output voltage is continuous and adjustable. There are 5 maximum test voltages under your order, 10 KV, 15 KV, 20 KV, 25 KV, and 30 KV.
3.The tester electrode using bead chain, the length of chain, the size of beads, the width of electrode, etc all can meet standard requirements.  The diameter of tested wire and linear velocity can by raised when you place an order. We will meet your requirements by design.
4.The high voltage part is completely closed in the box, the box is installed with grounding screw. The electrode box is equipped with interlock switch, open the lid can automatically stop the high voltage. Electrode groove and mechanical interlocking and grounding can ensure person and equipment safety.
