Can be customized according to customer requirements.

CATHODIC ISOLATOR? The CATHODIC protection current is blocked in the insulation measures, such as insulation joint or insulation flange at one end, and once the insulation measures of two real voltage exceeds the preset threshold value, the CATHODIC ISOLATOR? It will do its job, direct excess current into the ground.

Internal resistance: less than 1 ohms. The product is easy to install, the use of general American NEMA4 scale industrial grade electric cabinet, strong and safe.

CATHODIC ISOLATOR? The product has the following advantages:

■ No maintenance required

■ Solid state structure

■ Automatic fail-safe design

■ No electrolytes

Function indicators

Appearance: The main body is steel/cast aluminum/fiberglass shell, can be customized, waterproof and explosion-proof.

5. Make the operation of cathodic protection system more economical

Through the following functions, a CATHODIC ISOLATOR? The maintenance cost and operation cost of the cathodic protection system can be reduced. CATHODIC ISOLATOR? The discharge of the ground grid is not affected at all, and only the dc power required for cathodic protection is retained in the circuit. ■ AC interference current

■ AC induced voltage

■ Lightning/surge

The above functions ensure strict implementation of NEC, CSA, IEC, BSI and ATEX electrical insulation requirements.

Electrical insulation has the following three main advantages:

■ The cathodic protection current is completely limited to the surface of the protected component, so that it is evenly polarized to provide even protection.

Product selection parameters

1. Ac fault current value

Available in 7,10,20,30,40,50 kA -- 1 cycle @ 50hz RMS.

■ Prevent galvanic corrosion current between different metal components.

Contact your local power department to determine the current value.

■ Eliminate the interference of dc stray current. 4, static AC induction electrical interference value @ 50Hz RMS

Select values in the range 0 to 100 amperes: 12,24, 36,48,75,100 amperes

According to many years of practical experience of cathodic protection experts, 12 amps is generally selected.

3. Multiple protection

CATHODIC ISOLATOR? Can resist the following electrical interference:

■ AC stray current

S thunder and lightning

■ AC induction

■ Power supply equipment startup surge

In order to protect the safety of staff and equipment, a CATHODIC ISOLATOR? It is an indispensable equipment for electrical insulation.

4, the quality is safe and reliable

Unique circuit design makes the product agile, responsive, with overload safety protection, no maintenance. Each hub component is carefully selected and precisely installed.

Size: about 60×40×30mm, slightly varying with different models.

■ Control ac stray current

■ Ac induction

■ Provide lightning protection for equipment including rectifiers

■ For fuel equipment, tubular cables and other protected components, equipment and its contact with the electrical grounding network to play a decoupling role

. Depends on the voltage drop of the cathodic protection loop.

2, safe cathode insulation

Cathode insulation is a high level of electrical insulation. For example, a safe operating voltage of no more than 15 volts is required in the general design. The cathode insulation junction is subject to stringent requirements, complying with the US National Electrical Code (NEC), and the prevailing safety handling regulations around the world.

2, surge/lightning protection parameters

Nominal discharge current (8/20μs) low: 100kA

3. Voltage threshold

The RMS valid value is 3 volts, 6 volts, generally choose 3 volts.

Product features

1. Effective cathodic protection

Only when the protected member is in a state of electrical insulation (completely disconnected from other metal members, conductors, etc.) can the applied cathodic protection be even and effective. Back mounting bracket attachment with wiring end and test terminal at bottom.
