In photovoltaic power plants, in order to gather a large number of components and enter the inverter, we must rely on cables and connectors. Photovoltaic connectors are the key components of photovoltaic power generation systems, including components, junction boxes, controllers, inverters, etc.

Photovoltaic systems are exposed to wind and rain, hot sun, and extreme temperature changes for a long time. Connectors must be able to adapt to these harsh environments. It is not only waterproof, high-temperature resistance, UV resistance, but also tactile protection, high current-carrying capacity and high efficiency. At the same time, low contact resistance is also an important consideration. All of these must also run through the entire life cycle of the photovoltaic system, at least 25 years.

A waterproof connector is a connector that can be used in an environment with water and can ensure that the internal mechanical and electrical properties of the connector can be used normally under certain water pressure.

Protection level system

IP (INTERNATIONAL PROTECTION) protection level system is drafted by IEC (INTERNATIONAL ELECTRO-TECHNICAL COMMISSION). The electrical appliances are classified according to their dust-proof and moisture-proof characteristics. The foreign objects referred to here contain tools, and the palms, fingers, etc. of the person should not touch the live parts of the appliance to avoid electric shock. The IP protection level is composed of two numbers. The first number indicates the level of the appliance from dust and the intrusion of foreign objects. The second number indicates the degree of airtightness of the appliance against moisture and water intrusion. The larger the number, the higher the level of protection.

Advantages of waterproof connector

• Excellent sealing performance. The highest waterproof level of the waterproof connector can reach the IP68 standard.
• The waterproof connector is an internationally certified product, which has obtained CE certification, low voltage directive, WEEE directive and OOHS directive. These proofs guarantee the quality of the waterproof connector and its irreplaceable market position.
• The waterproof connector is a product with high quality and high design for a working environment with water. The equipment not only guarantees to provide customers with reasonable connection schemes but also brings a sense of safety and reliability.
• The waterproof connector has the characteristics of a fast and convenient installation.

SUNKEN can provide solar connectors with various waterproof grades, which can be used in various environments. If you need it, please contact us.
