DDZ Live indicatorDetailed product description：

The DDZ live indicator is used in fully insulated equipment such as cable branch boxes, box transformers, and ring main units. Due to the fact that all live components are fully insulated, operators cannot determine whether the line is operating normally. In response to this situation, we have developed a live indicator specifically designed for fully insulated equipment, which can be installed on Cooper Corporation and other domestically produced cable connectors in the United States. Remind operators and maintenance personnel whether the circuit is live based on the flashing status of the indicator light.

Design Principles
The electric field energy of the charged equipment is induced at the testing point, and when the electric field energy accumulates, it causes a flash. The flashing frequency varies with the change of system voltage.

Terms of Use
Can be installed at testing points on 200A or 600A cable heads.
The indicator is fully insulated and sealed, suitable for various climates

Installation and Usage

The live indicator can be installed when the cable head is live. Generally, the installation operation should be carried out after disconnecting the power supply to the circuit and cable head.
Use an insulated operating rod to remove the protective cap from the cable head test point.
Clean and dry the testing point, and lubricate the inner surface of the indicator installation with silicone grease.
Hook the operating hole of the indicator with an insulated operating rod, insert the live indicator into the testing point, and rotate it to the appropriate position.
After the line is re energized, the indicator light of the live indicator starts flashing, indicating that the line is live.
