Symmetrical Array & Voltage Configuration Matrix

The Eaton Cooper Power series symmetrical deadbreak T-connector infrastructure is tightly structured across dedicated catalog codes to handle distinct insulation outer diameters and core dimensions:

• Low-Range Conductor Layouts (35 mm² – 70 mm²): Utilizing specialized inner stress relief cones tailored for tight core clearances in utility branching circuits.
• Mid-Range Distribution Layouts (95 mm² – 240 mm²): Precision-calibrated to fit standard domestic and import single-phase or three-phase underground industrial networks.
• High-Stress的大截面 Layouts (300 mm² – 400 mm²): Utilizing rugged heavy-gauge bimetallic inertia-welded compression connectors built for wind array clusters and solar farm step-up loops.

Material & Structural Characteristics

• Direct-Molded Peroxide-Cured EPDM Rubber: Formulated, mixed, and molded entirely in-house to create a uniform, high-density insulation body that resists chemical oxidation and polymer tracking in severe environments.
• Semi-Conductive External EPDM Shielding Screen: Heavy-duty, molded outer skin that remains at absolute zero earth potential during live grid operation, ensuring 100% deadfront safe operator exposure.
• Pre-Molded Internal Geometric Stress Relief Cone: Advanced stress cone profile formulated to systematically smooth out high-voltage electrical field concentrations around the cable screen break.
• Tin-Plated High-Torque Double-Headed Clamping Screw: Heavy-gauge brass clamping hardware ensures low contact resistance and eliminates thermal drift under constant transformer vibration.
• Molded-In Screen Earthing Eyes: Features integrated, low-impedance grounding loop links pre-molded into the outer jacket to allow fast connection of copper earth drain lines.
• Dual Capacitive Test Points with EPDM Protective Caps: Equipped with an internal capacitive test point under a watertight grounding shield cap to allow safe circuit voltage status checking via standard line indicators.

Product Functions

1. Symmetric High-Voltage Potential Balancing: The symmetrical T-body design distributes physical installation stress evenly across switchgear bushings, minimizing mechanical bending moments in compact cabinets.

2. Deadfront Hermetic Submersion Shielding: Establishes a 100% fully screened, fully submersible, and dust-tight cable connection link that operates safely even under long-term direct water submersion.

3. Sectionalizing Grid Isolation Flexibility: Serves as a versatile disconnect terminal block; its rear-facing C-interface can be safely sealed with an epoxy insulating plug or expanded with rear coupling surge arresters.

Key Features

1. Zero Safe Phase Air Gap Requirement: Fully insulated deadfront geometry removes the need for standard phase-to-phase air separation clearances, dramatically down-scaling the total footprint of switchgear enclosures.

2. Tool-Free Quick Field Deployment: Requires no specialized hydraulic field-heating or chemical wrapping tapes; the entire component block is ready for full-load energization immediately after securing the tightening stud.

3. Non-Aging Bio-Fluid Chemical Compatibility: Formulated using premium polymers proven to maintain total structural stability and zero swelling when fully submersed in hot transformer mineral oil or plant-based Envirotemp FR3 fluids.

4. 100% Factory Partial Discharge Certification: Every production unit undergoes definitive automation quality tests including high-pC micro-volt screening, 100% partial discharge testing under 10 pC thresholds, and periodic X-ray integrity analysis.
