Product Specifications

Product Name: Eaton Cooper Power Series IEC Shielded T-Body Rear Plug-in Surge Arrester

OEM Model Configuration: DSA1236-10-45 (36 kV Class Base Designation)

Maximum Rated System Voltage (Um): 36 kV rms Distribution Networks

Nominal Discharge Current (In): 10 kA Symmetrical Peak

D.C. Reference Voltage Threshold: ≥ 64.5 kV Peak (Factory verified at 1 mA continuous current test cycle)

Mating Interface Compatibility: Standardized IEC Interface C Profile (Secured via high-torque rear-end stainless steel hardware blocks)

Material & Structural Characteristics

• Peroxide-Cured EPDM Outer Shield: Formulated from premium conductive EPDM elastomer that guarantees the entire external surface remains at safe earth potential during live grid operations.
• Solid Metal Oxide Varistor (MOV) Matrix: High-density, non-aging zinc oxide varistor disk stacks precision-calibrated to deliver immediate, symmetric impulse attenuation without thermal drift.
• Rear Piggyback Threaded Interface: Integrated C-interface rear plug assembly engineered with robust connection architecture to expand existing circuit branches effortlessly without replacing front cable terminations.
• Heavy-Gauge Tinned Copper Ground Braid: Pre-assembled high-conductivity flexible copper braid secured with a rugged stainless steel bolt to minimize grounding path impedance.

Product Functions

1. Piggyback Expansion & Branch Protection: Mounts directly onto the rear-facing insulating plug of an operational 36 kV 630A/1250A front T-connector, adding critical lightning and switching overvoltage protection within tight cabinet clearances.

2. Deadfront Electrical Shielding: Establishes a 100% fully shielded, fully submersible, and dust-proof insulated barrier that removes the need for minimum air-gap phase separation distances inside switchgear enclosures.

3. Transient Energy Absorption: Acts as a highly responsive voltage-dependent nonlinear valve that safely drains lightning surges to ground, resetting instantaneously to a micro-amp leakage open state once the surge passes.

Key Features

1. Renewable Grid & Wind Farm Optimization: Built to endure the punishing continuous operating voltage loads and tracking stresses standard in industrial solar networks and offshore wind array cabling blocks.

2. Zero Special Tool Installation: Utilizes standard internal hex-socket wrenches for terminal stud tightening, streamlining field deployment for utility linemen without needing specialized hydraulic tension tools.

3. Dual Medium Chemical Compatibility: Formulated with structural materials tested to guarantee zero degradation or chemical outgassing when completely submersed in hot transformer mineral oil or bio-based Envirotemp FR3 dielectric fluids.

4. 100% Precision X-Ray Production Screening: Every single DSA1236-10-45 unit undergoes definitive internal X-ray void inspection, micro-pC partial discharge verification, and full-load voltage withstand pre-shipment isolation tests.
