HydraElectric Brochure

With TE, you have unlimited opportunity with one of the widest ranges of underwater electrical and fiber optic connectors available anywhere in the world. This range of connectors covers not only optical, signal, and power, but hybrid connectors mixing these capabilities in a single unit. Our broad range of cable, connectors, penetrators, sensors, and switches gives you the flexibility to configure the ideal connector system for your most extreme applications.

The release of our HydraElectric electrical wet-mate connector follows our field proven HydraLight connector in joining our subsea distribution portfolio Modular in design with few parts and qualified to 4,000m, it is manufactured from Super Duplex stainless steel for excellent corrosion resistance and strength, and boasts up to a 30 year design life.

Contact Configurations

The connector bodies and shells are same size for all 3 contact configurations (4, 7 and 12). This enables flexible production and assembly processes and many configurations from few parts. Even though the external geometry is the same, the 3 different contact configurations must not be mated with each other. Damage will occur if a connector is mated
with a different configuration. To further differentiate the configurations all connectors are equipped with color coding identifying the relevant configuration.

Ethernet Capabilities

The 12 contact version of the HydraElectric has Ethernet capabilities which allows for data transfer speeds at 100 Mbit/s. It is qualified according to SEAFOM TSD-02 which includes the following standards for CAT 5 (100 Mbit/s); IEEE 802.3-2012, ANSI/TIA/EIA-568-A, ISO/IEC 11801:1995(Class D), and SIIS Level 3.

Tests performed are:

  • Insertion Loss
  • Return Loss
  • NEXT Loss
  • FEXT Loss

HydraElectric Connector Accessories

A variety of accessories can be provided to work in conjunction with the HydraElectric connector range. These are available for all modes of operation, ROV, Manual and Stab + pin
and socket gender.:

  • Flying dummy connectors for subsea use, with/without looping of contacts
  • Panel mounted parking connectors for subsea use, with/without looping of contacts
  • Dust caps for topside use only, universal with regards to mode of operation, number of contacts and electrical gender. The same dust cap can be used for both pin and socket connector, for ROV, Manual and Stab Plate
  • Test connectors for topside use, with Raychem SPEC 44 AWG 16 wiring or Ethernet compatible wiring as standard. The test connectors are universal and can be used for any mode of operation; ROV, Manual and Stab Plate
  • Pin gender dummy connectors and parking places are o©ered as universal with regards to the number of contacts in black colour
  • The use of dummy connectors or parking places is recommended when connectors are exposed to seawater. Maximum exposure time in subsea environment without sunlight exposure and with temperatures below 10°C is 30 days. In environments with high marine growth, a cleaning of connectors may be required before mating

 

HydraElectric ROV Connector Series

The HydraElectric ROV series is designed to be operated by ROV’s in some of the most harsh environments. They are designed and tested to help meet the rough handling and forces potentially seen during ROV operation, both mated, de-mated and during the mating sequence. The alignment mechanism of the connector bodies helps ensure proper alignment before pin contacts engage the socket contacts and electrical contact is established.

Handling the Rigors of the Harshest of Environments

TE has a wide experience in advanced material technology. Combining it’s years of experience and a track record in subsea environments TE are able to provide products utilizing plastic materials in flanges and handles, which allows a beneficial ratio between weight, flexibility and mechanical strength.

Both the ROV handle and panel flange is made of plastic materials carefully selected to help meet the requirements of many of the harshest environments. At the same time the materials have to be flexible enough to avoid damage during operation. The materials are tested and stressed to their maximum to ensure that they perform according to requirements.

The latching mechanism provides proper locking of connector halves in a mated position. The latch member is allowed to expand freely without external limitations. It is made of a plastic material which minimizes corrosion and calcium carbonate build up caused by cathodic protection of subsea structures. The latch mechanism provides visual positive latch identification and contains a minimal number of parts. The latch member can easily be replaced both topside and subsea without disengaging the connector.

 

HydraElectric Manual Mate Connector Series

The manual mate connectors are designed to be operated manually. They are typically mated/de-mated topside, on surface or in shallow waters, but they are of course designed and tested to be used at full design depth of 4,000m. A threaded engaging nut provides proper mating of connectors with a minimum amount of force required for operation.

Panel flanges can be front and rear mounted. The same flange is used for both options, but a slotted interface might be required depending on application.

Bulkhead Flange
The bulkhead connectors are used in applications where there is a need for a sealing surface towards a separate oil filled and pressure compensated/balanced volume. These are available for ROV and Manual mode of operation.

Sealing is provided through dual o-ring barriers, with one radial and one axial o-ring. Bootseals provide the internal barrier towards the solder pots. It is suitable for several applications such as:

  • Retrievable canisters and modules
  • Junction boxes
  • Control modules
  • Power distribution modules

The plastic material in the flange provides electrical isolation between the connector and the CP (Cathodic Protection) system.

Panel Flange

The same panel flange is used on ROV and Manual connectors. Made from plastic materials carefully selected to help meet the requirements of many of the harshest environments.

At the same time the materials have to be flexible enough to avoid damage during operation. The materials are tested and stressed to their maximum to help ensure that they perform according to specifications. This flange can be used for both front and rear mount. The flange and Part number is the same for both mounting options. The plastic material in the flange provides electrical isolation between the connector and the CP (Cathodic Protection) system.

HydraElectric Stab Plate Connector Series

The stab plate connectors are used as elements in a stab arrangement, providing movement and latching of the connectors. Stab connectors do not have a built in latching mechanism. The connectors are made of Super Duplex which provides excellent corrosion resistance and do not need to be connected to a cathodic protection system.

Stab Plate Mounting Details

One of the connectors in a mating pair must be provided with floating flange, allowing the connector to move +/- 1mm axial and radial. Flanges on stab connectors are 10 mm thick and are interchangeable between front and rear mount.

There is also a split flange option available for the stab plate connectors. This enables the connector to be front mounted, even when pre-terminated to a jumper or assembly.

Test Connectors

The test connectors are universal and the same connector can be used for all modes of operation; ROV, Manual and Stab Plate. The test connector bodies are in plastic material and they are not designed for subsea use.
