Product overview

315kVA 10KV oil-immersed Power Transformer

In the 10KV ultra-large capacity power distribution scenarios, the core pain points include insufficient equipment load capacity and frequent failures in complex environments. It is difficult to find oil-immersed equipment with a capacity of 315kVA that can balance stability and environmental adaptability when purchasing. The 315kVA 10KV oil-immersed power transformer can be directly paired with Box Type Substation for deployment, working collaboratively with High And Low Voltage Switchgear to operate efficiently. It can stably carry the ultra-large power distribution load and adapt to complex environments such as outdoors and high temperatures, effectively solving the core problems in procurement and usage.

This transformer core is designed for 10KV ultra-large capacity power distribution scenarios, covering large industrial parks, centralized power distribution hubs, large factories, and centralized power supply projects for photovoltaic power. It can be networked with transformers of the same specification to operate together, seamlessly connecting with Dry Type Transformers to flexibly meet the needs of different power distribution zones. It is equipped with an Electric Power Converter to optimize the efficiency of power transmission and is combined with Combined Photovoltaic Substations to achieve large-scale utilization of clean energy. The core value lies in its focus on stable output of ultra-large capacity, while also considering strong environmental adaptability and practicality. This reduces the frequency of equipment failures and downtime, and lowers the long-term maintenance and replacement costs for the purchaser.

Product Features 1.With an extremely large capacity, it can handle strong loads. The 315kVA capacity can meet the centralized power distribution requirements for large-scale scenarios. Its overload capacity far exceeds that of ordinary Oil Immersed Transformers. It is unlikely to experience overheating or shutdown failures during long-term full-load operation. 2. It has strong environmental adaptability. The sealed oil-immersed structure can prevent dust, moisture and high temperatures, and is suitable for outdoor and complex industrial environments. When used in conjunction with Box Type Substation and High And Low Voltage Switchgear, the operational stability is not affected by the environment.

Tips for Use 1.During installation, it is necessary to ensure a firm fixation and provide sufficient cooling space. The connection of the lines with High And Low Voltage Switchgear and Box Type Substation should be carried out in a standardized manner to avoid poor contact. 2. The key points of daily maintenance include checking the insulation oil level, oil quality and sealing condition. The oil quality should be tested once every six months to prevent oil leakage. Basic maintenance does not require professional operation.

Frequently Asked Questions Answered Q1: Can this transformer be used in conjunction with Combined Photovoltaic Substations and Electric Power Converter? A1: It is fully compatible. Standard interfaces are reserved, and it can directly connect to the Combined Photovoltaic Substations for centralized photovoltaic power supply, and be combined with the Electric Power Converter to optimize the distribution of electrical energy. No additional interface modifications are required.

Design features

What the design is built around

Low-loss magnetic core

Cold-rolled grain-oriented silicon steel and a stepped core reduce no-load loss and audible noise.

Sealed tank construction

Welded tank, quality-gasketed cover and pressure-tested seals reduce oil leakage risk in outdoor duty.

Thermal margin for hot climates

Cooling surfaces and oil volume are selected for high ambient temperature and cyclic loading.

System compatibility

MV terminals, cable boxes and LV bushings are matched to the switchgear and protection scheme.

Buyer questions

FAQ for 315 kVA 10 kV Oil-Immersed power Transformer

What is 315 kVA 10 kV Oil-Immersed power Transformer best used for?
This model is specified at 315 kVA and 10 kV. It is used where the site load, fault level and environmental conditions match the approved datasheet. Share the load profile, ambient temperature, altitude and grid code and the design can be checked against the application.
What is the typical lead time for 315 kVA 10 kV Oil-Immersed power Transformer?
Standard distribution units typically ship in 25-40 days after drawing approval. Large power transformers and integrated stations are scheduled by design review, core and winding production, tanking, testing and packing. The exact date is confirmed in the quotation.
Which standards and tests are supplied?
The transformer family is designed to GB 1094.1, GB/T 6451 and IEC 60076. Routine tests include winding resistance, ratio, impedance, no-load loss, load loss, insulation resistance and power-frequency withstand. Type and special tests are available on request.
Can the transformer be customised for 60 Hz or a hot climate?
Yes. Frequency, ambient temperature, altitude, enclosure, corrosion class and terminal arrangement are project inputs. The design is adjusted before production, and the approved datasheet becomes the inspection basis.
How do I choose between copper and aluminium windings?
Copper gives higher short-circuit strength and a more compact winding; aluminium can reduce first cost for lightly loaded units. The choice depends on fault level, load profile, loss evaluation and the buyer's specification. Both are available.
