As photovoltaic (PV) systems become more widespread, ensuring their safety and reliability is essential, especially in preventing lightning and surge interference. Low Voltage Surge Protection Device (SPD) play a critical role in PV systems by reducing the risk of equipment damage. Here are some important considerations for applying SPD in PV systems.

Ⅰ. Selection of SPD

PV systems have relatively high DC voltages, so it’s essential to choose SPD  that match the system’s voltage level. Ensure that the Voltage Protection Rating (VPR) of the SPD meets the safety requirements of the equipment. Pay special attention to the differences between DC and AC SPD.

Ⅱ. Installation Location of SPD

The installation location of the SPD is crucial; it should be as close as possible to key equipment like inverters and controllers. Additionally, SPD need to be installed at the equipment input to ensure that surges are suppressed before reaching the devices.

The proper design and installation of the grounding system in a PV system contribute to the effective performance of the SPD. It’s recommended to use a low-impedance grounding system to ensure that surge currents can be quickly dissipated, reducing the impact on the system.

Ⅳ. Regular Maintenance and Inspection

To maintain the effectiveness of SPD, regular inspections and maintenance are necessary. After stormy seasons, promptly replace any aged or failed SPDs to ensure the safe operation of the PV system.

With proper surge protector selection, installation, and maintenance, the surge resistance of PV systems can be significantly enhanced, extending their lifespan and ensuring stable operation.

Choosing the best casters for outdoor use involves considering durability, load capacity, maneuverability, and resistance to outdoor elements. Outdoor casters are essential for applications like moving furniture, equipment, or garden structures, where they need to withstand uneven surfaces, moisture, and temperature changes. Here’s a quick guide to choosing the right caster for outdoor use.

Material

Outdoor casters are typically made from durable materials that can endure harsh environments. Swivel stainless steel casters, for example, are corrosion-resistant and can withstand moisture, while polyurethane casters provide a smooth roll over rough surfaces and resist damage from chemicals, oils, and abrasions.

Industrial rubber casters are also popular for outdoor use due to their flexibility and ability to handle rough and uneven ground. Hence, cast iron casters are not suitable for outdoor use.

Tread Type

A soft-tread one, such as rubber or polyurethane, shock absorbing casters from uneven surfaces, making it suitable for outdoor use. Soft-tread casters also provide good traction on wet surfaces, reducing the risk of slipping. For heavy-duty tasks, consider casters with pneumatic (air-filled) tires, which offer excellent cushioning and grip on varied terrains.

Top Recommendations

Polyurethane Casters: Known for durability and smooth operation, polyurethane casters handle rough outdoor surfaces well and are resistant to various chemicals, making them ideal for gardens and outdoor warehouses.

Stainless Steel Casters: Perfect for environments where moisture is a concern, these casters resist rust and are suited for outdoor furniture and equipment that might be exposed to rain or snow.

Pneumatic Casters Wheels: Equipped with air-filled tires, these are ideal for heavy-duty applications on rough or uneven ground. They offer great shock absorption, making them suitable for outdoor activities and construction sites.

When selecting casters for outdoor use, consider the specific environment and load requirements to ensure safety and longevity.

When choosing a Heavy Duty Outdoor Caster Wheels, there are several important factors to consider:

Wheel Grip

Excellent grip is essential when choosing wheels that can carry heavy loads outdoors,such as Heavy Duty Industrial Trolley Wheels. These wheels are usually designed for high performance, have excellent shock absorption, and can easily navigate rough or uneven surfaces.

Turning Radius

The turning radius refers to the amount of space required for the reel to swing or turn. For Outdoor Industrial Metal Casters, choosing a larger turning radius reduces the force required to change direction, providing smoother, more efficient movement.

Maneuverability

Efficient maneuverability is especially important for outdoor spaces. Heavy-duty swivel wheels allow for greater flexibility and smoother movement than fixed casters. For precise control, consider a swivel lock or heavy duty kingpinless casters design that eliminates pan head errors and provides greater steering accuracy.

Load Capacity

Before choosing a heavy duty caster, it is important to understand the total load capacity of the caster set. This includes not only the weight of the object, but also the weight of the cart or equipment the pulley is attached to.

Conclusion

These are the most important considerations when choosing a heavy-duty outdoor caster. YLcaster is one of the leading industrial casters and wheels manufacturers in China, offering a wide range of options to suit every need.

In our product range, you can find different types of castors for a variety of purposes. In brief, we will summarize some of the most common types of castors and their applications.

Swivel castor or rigid castor?
Practically all castors are divided into two categories. You can either choose a swivel castor that is able to rotate in any direction, even when carrying a heavy load. If you need the wheel to move in a straight line you can choose for a rigid, also known as fixed castors, which can not be steered but can only move back and forth.

Locking castors with brake system
You specifically need locking castors when you need to move up and down a slope or when you want to prevent the load to suddenly move. In most cases, a castor with a lock is needed for safety, either to prevent the load from damaging or to ensure a safe working environment. The brake system is traditionally mounted on the swivel castor as it combines the braking of the wheel rotation with the braking of the horizontal “swiveling” rotation.

Castors with locks are often used on containers, platforms, scaffolding, furniture or containers. There are different castor brake types that you can use, you can choose for:

- A brake that presses only the spinning of the wheel, these are single braked castors.

- A double working brake that brakes the rotation of the wheel and the swivelling of the swivel castor.

- Or a brake that pushes on the floor and lifts up the platform or trolley, this can be levelling castors or floor brakes, also known as truck locks.

Plate castors, bolt hole castors or stem castors
Plate castors are used in a wide variety of applications and are available as both rigid castors as well as swivel castors. The mounting plate makes it easy to attach the wheels to the appliance which needs to be able to move. The mount plate consists of a rectangular steel plate with 4 drill holes to fasten the castor with. Depending on your preferences or requirements we can create various hole patterns on our top plate castors.

Stem castors are mostly used when there is little space to connect your castor on. The stem on these castors is the connection point for the wheel. These stem mounts are often threaded, but we can also provide them non-threaded in a round or square shape with mounting holes or expandable stems.

Bolt hole castors are a certain type of stem castors that you can fasten through the centre of a swivel head. These castors are often used on equipment like trolleys, carts or medical equipment.
