COSCO manufactures a complete line of rugged Electric Feed-thru Systems (Penetrators) for wellheads used in Electrical Submersible Pump Applications. COSCO connector systems represent the utmost in reliability, simplicity, versatility, and convenience. COSCO wellhead penetrators are adaptable to any application, onshore or offshore under the harshest conditions.
Several different options are available to meet any need:
- Two-piece 90-degree top entry
- Three-piece 90-degree top entry
- Side entry systems
- Fail safe systems
- A variety of pigtail cable types and sizes are available to meet any application or service.
The lower penetrator is the key to the reliability of COSCO Connector Systems. It’s unique design eliminates the need for a connection in the annulus, thereby eliminating a weak spot. Corrosion resistant stainless steel is used for the housing and flange of the connector. The electrical conductors are insulated by an inner Viton seal and an external Torlon face block. These components work in conjunction to provide superior protection from corrosive well-bore fluids and pressure damage.
The lower penetrator bolts to the bottom of the tubing hanger by means of a flange. The upper connector bolts into the top of the electrical port located on the tubing hanger. The lower connector bolts into the bottom port in a similar manner. Each connector is secured in place by means of a flange and four bolts. The lower connector pigtail is spliced to the down hole power cable. No special tools are required for installation.
COSCO wellhead penetrator systems allow a lower profile x-mas tree assembly. The side entry system is specifically designed for applications where low tree profiles are critical, such as offshore applications.
COSCO connectors can be installed into most existing wellhead equipment for conversion to Electrical Submersible Pumps systems, or to replace other types of electric feed-through systems.
