Trafindo Hermetically-Sealed Oil Type Distribution Transformer

Trafindo Hermetically-Sealed Oil Type Distribution Transformer – Low-Maintenance Heavy-Duty Industrial Power Solution

Product Overview

The Trafindo Hermetically-Sealed Oil Type Distribution Transformer is a heavy-duty power distribution asset engineered to deliver maximum electrical reliability without demanding complex routine maintenance. Manufactured by PT Trafoindo Prima Perkasa, this sealed-tank transformer fully isolates dielectric oil from ambient air exposure. This design eliminates the need for an open conservator tank and silica gel breathers, preventing oil oxidation and dielectric breakdown over extended operating periods. Equipped with integrated HV and LV Cable Termination Boxes, this transformer provides robust protection against harsh weather elements, industrial dust, and accidental human contact.

Technical Specifications of Trafindo Hermetically-Sealed Transformer

Engineering Features & Hermetically-Sealed Advantages

The structural configuration of the Trafindo Hermetically-Sealed Transformer integrates advanced fluid isolation technology engineered for demanding environmental conditions:

• Fully Airtight Sealed Tank Structure: Dielectric fluid remains completely sealed within the steel enclosure without atmospheric contact. This eliminates moisture ingress and oxygen exposure, preserving fluid breakdown voltage.
• Elimination of Silica Gel Maintenance: Operating without atmospheric breathing removes the need for silica gel breather replacement, significantly reducing annual maintenance costs.
• Integrated Cable Termination Boxes: Protective steel enclosures over HV and LV bushings shield terminal connections from salt spray corrosion, industrial airborne dust, wildlife interference, and accidental physical contact.
• Optional Nitrogen Gas Cushion ($N_2$): A compressed nitrogen cushion above the oil surface absorbs thermal expansion during peak load cycles, keeping internal tank pressures balanced.
• High-Grade CRGO Core & Winding Architecture: Utilizes Cold-Rolled Grain-Oriented silicon steel laminations to minimize standing no-load losses and exciting currents.

Energy Efficiency & Total Cost of Ownership (TCO) Analysis

Deploying a Trafindo Hermetically-Sealed Oil Type Distribution Transformer yields substantial financial savings across decades of operational service:

• Reduced Operating & Maintenance Costs (O&M): Removing routine oil sampling and breather gel replacements minimizes annual servicing overheads.
• Extended Fluid Lifespan: Total isolation from atmospheric oxygen prevents thermal sludging and oxidation, eliminating frequent fluid purification procedures.
• Compact Physical Profile: Omitting the top conservator tank reduces overall equipment height, simplifying installation inside space-constrained indoor substations.

Example Project Reference Specifications (Reference Data)

Note: The technical data below represents an example project reference specification for a 1500 kVA transformer unit previously manufactured. Actual dimensions, weights, and parameters for your order are customizable (project dependent) based on specific engineering requirements, voltage ratios, and requested accessories.

Advanced Protection Instrumentation & Substation Automation

To safeguard mission-critical power networks, Trafindo Hermetically-Sealed Transformers accept optional integrated protective devices:

• Pressure Vacuum Gauge: Measures internal tank pressure and vacuum conditions directly for continuous structural monitoring.
• Pressure Relief Device (PRD): Vents excessive internal pressure instantaneously during severe internal faults to prevent tank deformation.
• Contact Thermometer (Oil Temperature Indicator): Tracks liquid temperature variations and provides electrical contacts to trigger warning alarms or automatic circuit breaker trips.
• Multifunction Hermetic Sensor (Optional DGPT2 / RIS Relay): Combines internal pressure monitoring, liquid temperature tracking, and gas accumulation detection into a single integrated protection module.

Regulatory Compliance Standards & Quality Certifications

Every Trafindo transformer is built in manufacturing plants certified to ISO 9001:2015 for Quality Management, ISO 14001:2015 for Environmental Management, and ISO 45001:2018 for Occupational Safety. Design and assembly processes comply strictly with IEC 60076 specifications and PLN guidelines (SPLN). Equipment comes backed by official Type-Test Certificates from independent laboratories and LMK PLN approval, ensuring operational safety in the field.

Target Industrial Applications & Mission-Critical Facilities

The advantages of a sealed tank construction and protective cable termination boxes make this transformer ideal for specialized installation environments:

• Commercial High-Rises & Data Centers: Perfectly suited for indoor substation rooms due to reduced vertical height profiles and low fluid leakage risks.
• Coastal Industrial Zones & Humid Sites: Hermetic sealing and cable termination boxes protect terminals from saline air corrosion and high humidity.
• Chemical Plants & Processing Facilities: Prevents airborne corrosive gases and industrial dust from contaminating internal insulation fluid.
• Utility Networks & Oil and Gas Operations: Provides constant power delivery for onshore pumping stations and industrial distribution yards.

Installation Guidelines, Field Testing & Maintenance

Ground-mounted placement requires a reinforced concrete pad foundation engineered to support total equipment weight evenly. Prior to grid connection, perform standard Site Acceptance Testing (SAT) such as insulation resistance testing (Megger), winding ratio checks (Turns Ratio Test), and valve tightness inspections. Periodic maintenance focuses on cleaning cable termination boxes from dust and checking pressure vacuum gauges.
