The water depth below 200 m is called the deep sea by scientists. The special environmental characteristics of the deep sea and the wide range of unexplored areas have become the latest research frontier of international earth science, especially marine science. With the continuous development of science and technology, more and more equipment in the deep sea can be applied, and the deep-sea watertight connector is the most effective way to achieve the deep-sea environment between the equipment system and the system power distribution, signal transmission, communication, and other functions. Watertight connectors in the realization of the above functions at the same time, but also to withstand the external seawater high pressure, corrosion, low temperature, and other environmental impacts, and even need to achieve long-term residence in the deep-sea environment, which also brings challenges to the deep-sea watertight connector material selection, structural design. The existing deep-sea watertight connectors are mainly in the form of rubber moulding, rubber or epoxy resin and metal bonding, etc. Around the different application scenarios, the types of deep-sea watertight connectors are also being expanded.

Deep-sea watertight connectors are an important part of deep-sea equipment to achieve power distribution, signal transmission and communication links. Connectors are the key to successful subsea applications. Unless you identify the correct subsea connector for your project, it could die in the water or at the very least require frequent and expensive repairs. Underwater connectors, also known as wet connectors, subsea connectors, or marine connectors, are designed to be plugged or unplugged in wet environments and can withstand the most extreme environments, from corrosive seawater and pressure to vibration and shock. Traditionally, underwater connectors have relied on watertight seals. Over time, several variants have been developed to achieve this.

According to different application scenarios, deep seawater tight connector’s structure and watertight forms are also different, in order to adapt to the high-pressure environment of large depth seawater, deep seawater tight connectors more than take two ways to resist external high pressure. First, the use of oil-filled compensation type of watertight connectors, see oil-filled watertight cable, through the cable encapsulated in oil-filled line pipe to achieve and the effective isolation of the external seawater, so as to ensure the electrical performance, the external seawater high pressure will be passed through the internal compensation oil to all parts of the cable, the key to such watertight connectors is the encapsulation and sealing of the plugging part of the cable. The second is the use of rubber overall vulcanisation and other forms of watertight connectors, through the overall vulcanisation of the cable encapsulated in rubber-like materials to achieve effective isolation from seawater, and rubber and metal bonding is a key technology for watertight connectors of great depth, the bonding performance is good or bad to a large extent determine the life of the watertight connector.

Frankstar Technology is now offering self-developed connectors. It fits perfectly with existing connectors on the market and is the perfect cost-effective alternative.
