Product Description

Solid-state decoupler for cathodic protection system

Product Introduction
I produced the decoupling technology uses advanced solid metal shell , can effectively control the pipeline safety effects of stray currents or lightning alternating current on buried pipelines , extending the life of the pipeline. At the same time , but also to prevent harm and interference in the collection of stray current pipeline of human communication lines.
    Solid-state decoupling device (SSD) Series DEI company adhering to the corrosion of industrial corrosion products provide innovative tradition , using the company's own research and development of DEI 's solid-state technology . Since the SSD light weight , non-metallic shell, so it is widely used in the cathodic protection system.
    As DC isolation and AC-coupled devices , SSD is used to prevent cathodic protection current reaches a predetermined threshold voltage , while conducting alternating current induction . When the voltage exceeds the threshold voltage sought , SSD immediately switch to short-circuit mode , in order to provide overvoltage protection. When the overvoltage past , and automatically switch back to DC isolation mode. This mode of operation can be carried out many times , this is usually due to the AC fault currents or lightning currents cause . Standard voltage thresholding SSD for -2V / +2 V. The absolute value of the threshold voltage may be a voltage or peak voltage , the voltage at the switching occurs, the voltage across both ends of the spacer in the flow and exchange of the city and the peak voltage . This allows the clamp voltage across the terminals of the low SSD , very safe.
    Like most products with DEI , SSD through independent laboratory certification. Confirm compliance with all well-known American , Canadian and European standards. Inspection and certification and Demko performed by Underwriters Laboratories (Underwriters Laboratorics --- UL), thus obtained UL, CUI  column name and the CE mark. After certification , SSD can be used in dangerous situations ( class 2 area )

Range of Application:
1.Pipeline potential gradient pad ( grounding pads ) decoupling
2.The device over AC fault , lightning and switching transient voltage protection ( such as: insulation joints , insulating flange )
3.For safety , for de- coupling between the different metals , these metals may in some cases generate an AC coupling.
4.In the cathodic protection system, grounding electrical equipment exchanges and direct isolation
5.To reduce the AC voltage induced occasions
