Compact Prefabricated Substation (PTS) – Integrated MV/LV Power Distribution Solution

Product Overview

Our Prefabricated Compact Substation (also known as Package Transformer Substation or Box-Type Substation) is a fully integrated, factory-pre-assembled power distribution system. It houses three functional compartments within a single robust enclosure:

1. High-Voltage (HV) Compartment – equipped with SF6 gas-insulated Ring Main Unit (RMU) or load-break switches for incoming/outgoing cable connection and transformer protection.

2. Transformer Compartment – fitted with either oil-immersed or dry-type power transformer (50kVA – 2500kVA) for voltage step-down.

3. Low-Voltage (LV) Compartment – contains main circuit breakers, outgoing feeders, metering, and power factor correction (PFC) panels.

Designed for rapid deployment, this substation eliminates the need for traditional concrete building construction, significantly reducing civil works, installation time, and overall project cost. Each unit is fully wired, tested, and sealed at our factory, ensuring reliable "plug-and-play" operation upon delivery.

Key Features

• All-in-one integration – HV switchgear, transformer, and LV distribution in one compact housing, saving over 60% footprint compared to conventional brick-and-mortar substations.

• Factory pre-assembled & tested – reduces on-site installation time by up to 80%; minimize human errors and weather-related delays.

• Weatherproof & robust enclosure – IP54/IP55 protection (optional IP65) with anti-corrosion treated steel plates, GRP, or color-coated panels, suitable for harsh outdoor environments (–40°C to +55°C).

• Modular & flexible design – multiple layout configurations (single-row, double-row, L-shape) to adapt to site constraints.

• High safety standards – fully interlocked HV compartments, arc-flash protection, pressure relief vents, and fire-resistant partition walls between compartments.

• Low maintenance – sealed transformer with long-life oil or dry-type cast resin technology; SF6 RMU requires no gas replenishment.

• Remote monitoring ready – optional SCADA communication ports (RS485 / Ethernet / IoT) for real-time data acquisition and fault diagnosis.

• Eco-friendly options – available with biodegradable ester oil transformers or SF6-free insulation switchgear for green projects.

Available Configuration Options

We offer complete customization to match your distribution network requirements:

• HV side options: RMU (ring topology), load-break switch + fuse combination, or vacuum circuit breaker.

• Transformer options: copper or aluminum windings; mineral oil, ester oil, or dry-type; on-load or off-load tap changers; various vector groups (Dyn11, Yyn0, etc.).

• LV side options: fixed or draw-out switchgear; number of outgoing feeders (4 to 24 ways); automatic transfer switch (ATS); capacitor compensation (fixed or automatic).

• Enclosure options: steel plate, GRP (fiberglass), or stainless steel; single-skid or split-type for transport constraints; color matching (RAL code).

Application Scenarios

• Urban power grids – residential communities, commercial plazas, hotels, and hospitals.

• Industrial facilities – manufacturing plants, mining sites, oil & gas fields, and chemical plants.

• Renewable energy – solar PV farms, wind power stations, and energy storage systems (BESS).

• Infrastructure – airports, seaports, railway traction substations, and highway tunnels.

• Temporary & emergency power – construction sites, disaster relief, and remote area electrification.

• Telecom & data centers – reliable power backup and distribution for critical loads.

Frequently Asked Questions (FAQs)

Q: Can this substation be transported as a single piece?
A: For capacity up to 1250kVA, we offer a single-skid design. For larger capacities (≥1600kVA) or road transport restrictions, we supply split-type modules assembled on-site.

Q: Do you offer silent-type (low-noise) versions?
A: Yes. We can add acoustic enclosures or use dry-type transformers to reduce noise levels below 45dB(A) for residential areas.

Q: What is the typical lead time?
A: Standard configurations: 4 weeks. Custom engineered solutions: 6–8 weeks, depending on specifications.

Q: Do you provide installation service overseas?
A: We provide detailed manuals and remote guidance. On-site supervision and commissioning services are available upon request for an additional fee.
