We emphasize effective R&D investment management and production efficiency, particularly in diesel power generation. Our extensive experience in engineering applications and service management positions us as a forward-thinking enterprise, committed to delivering exceptional value and returns to our customers and various investment institutions.

What are the Features of a PowerLink Diesel Genset?

Our diesel generator sets are designed with advanced technology and a modular design, ensuring superior performance while maintaining cost-effectiveness. At PowerLink, we have an in-depth understanding of the entire equipment system, which includes the engine, generator, and other hardware components, as well as automation control and software, all developed independently by PowerLink.

What Types of Applications are PowerLink Generator Sets Suitable For?

PowerLink generator sets cater to a broad spectrum of continuous energy needs. Our smallest unit is 5KVA, ideal for households and small retail properties, and our largest is 3250KVA, capable of powering commercial buildings, hotels, hospitals, mines, factories, and even national power grids. Our generators are suitable for standby and continuous power supply in various sectors.

What are the Standard Components of Our Generator Sets?

Our generator sets include a diesel engine, alternator, elastic coupling, main circuit breaker, radiator, various filters (fuel, air, oil), steel chassis, silencer, accumulator, daily fuel tank, oil filling system, silent housing/container body, and a PLC control system.

How to Calculate and Analyze Return on Investment?

To analyze ROI, assess the local energy structure, including electricity and fuel costs, and monthly energy expenses. Our sales experts can then provide a detailed ROI analysis based on this information.

How to Choose New Power Generation Equipment?

Consider factors like installation cost, power generation efficiency, production and commissioning time, modular installation solutions, and operating expenses. PowerLink offers a wide range of diesel engines to ensure a fitting solution for every project.

Can the Generator Set be Used in Adverse Weather Conditions?

PowerLink generator sets are designed for harsh environments (recommended ambient temperature: -25℃ to 50℃, altitude ≤1000m), but using them in severe conditions should be avoided to extend their lifespan.

What is a Transfer Switch?

A transfer switch is a device that connects to your site’s power distribution system, enabling safe generator use by preventing backfeed into the main power supply.

How to Reduce Noise of Generator Set?

Methods include exhaust noise reduction using special silencers, reducing axial fan noise, and implementing sound insulation, sound absorption, and vibration isolation.

How Does the Generator Set Work with the Main Power Supply?

The generator set integrates with the stable mains power, automatically starting to supply power during an outage and switching back once the main power is restored.

What is the Product Lead Time and Shipping Method?

Standard product lead time ranges from 2 to 6 months. We use various carriers for delivery, offering tailored transportation plans based on the project's needs.

What Should I Know When Installing a Generator Set?

Installation requires attention to ventilation, cleanliness, exhaust pipe setup, foundation leveling, and reliable protective grounding. Ensure the reliability of the bidirectional switch and proper wiring of the starting battery.

How is Equipment Debugging Conducted?

Our team offers global commissioning services and remote technical support. Prior to commissioning, a spot inspection should be conducted following our after-sales department's checklist.

How to Protect the Alternator?

We use Thermomagnetic Protection (TMP), Leakage Protection, and Insulation Protection to safeguard the alternator against electrical faults.

What Happens if I Overload the Generator?

Continuous overloading can cause cooling system overheating, alternator winding overheating, decreased oil viscosity, and reduced generator lifespan. Operating within recommended load limits is crucial.

How to Calculate kVA/KW?

To calculate the power in kilovolt-amperes (kVA) or kilowatts (KW), multiply the voltage (in volts) by the current (in amperes) for single-phase systems. For three-phase systems, multiply the voltage, current, and the square root of 3 (approximately 1.732). Divide the result by 1000 to convert to kVA or kW as needed.

What is a Load Bank?

A Load Bank is a device that creates an electrical load to apply to a power source, like a generator. It simulates real electrical loads, enabling testing and validation of the power source's efficiency, performance, and reliability.

How to Measure the Power Requirement for My Load?

To measure the power requirement for your load, list all the electrical appliances or systems that will be powered by the generator. Calculate the total wattage by adding the individual wattages of these appliances or systems. This sum gives you an estimate of the power requirement. Ensure to consider both starting and running wattage for accurate assessment.

What is a Lighting Tower?

A lighting tower is a piece of mobile equipment which consists of one or more high-intensity electric lamps and a mast. Typically used at construction sites, outdoor events, or in mining operations, these towers provide essential lighting over a large area. Most lighting towers are powered by generators and are designed to be easily transportable and adjustable in height to cater to specific lighting needs.

What Should You Keep in Mind When Purchasing a Lighting Tower?

When purchasing a lighting tower, consider the following factors:

  • Illumination Area and Brightness: Ensure the tower provides adequate light coverage for your specific needs.
  • Power Source and Efficiency: Check if the tower is powered by a generator or electricity and assess its energy efficiency.
  • Portability and Setup: Look for a tower that is easy to transport and set up.
  • Durability and Weather Resistance: Ensure the tower is robust and can withstand the environmental conditions of your operation site.
  • Maintenance and Operational Costs: Consider the long-term maintenance requirements and operational costs.

What is an Air Compressor?

An air compressor is a device that converts power (using an electric motor, diesel, or gasoline engine) into potential energy stored in pressurized air (i.e., compressed air). It forces more and more air into a storage tank, increasing the pressure. These devices are commonly used in various industries for supplying high-pressure clean air to fill gas cylinders, power pneumatic tools, and for HVAC control systems.

What Should You Keep in Mind When Purchasing an Air Compressor??

When purchasing an air compressor, consider these key aspects:

  • Capacity and Pressure Requirements: Determine the air flow (CFM) and pressure (PSI) requirements for your tools or applications.
  • Type of Compressor: Choose between reciprocating, rotary screw, or centrifugal compressors based on your usage needs.
  • Power Source: Decide whether a gas-powered or electric compressor is more suitable for your work environment.
  • Size and Portability: Consider the size of the compressor for your workspace and if portability is required.
  • Noise Level: Especially important if the compressor will be used in noise-sensitive areas.
  • Maintenance Requirements: Understand the maintenance needs to keep the compressor running efficiently.
