COSCO CONNECTOR SYSTEMS represent the utmost in reliability, simplicity, versatility, and convenience. They are adaptable to any application, onshore or offshore under any condition. RELIABILITY The lower CONNECTOR is the key to the reliability of COSCO CONNECTOR SYSTEMS . Its unique design eliminates the need for a connection in the annulus, thereby eliminating a weak spot.

2 Corrosion resistant stainless steel is used for the housing and flange of the CONNECTOR , while the compound used to insulate the electric conductors and provide the pressure seal inside the body of the CONNECTOR is not susceptible to swelling or breakdown caused by wellbore fluids. The unique construction of the CONNECTOR includes a Torlon face block to protect against pressure damage. EASE OF INSTALLATION The lower CONNECTOR bolts to the bottom of the tubing hanger by means of a flange. The upper CONNECTOR bolts to the top of the tubing hanger and the connection between the upper and lower connectors is made within the electrical connection port of the tubing hanger. The lower CONNECTOR pigtail is spliced to the down hole power cable. No special tools are required for installation.

3 VERSATILITY Several different configurations 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. LOW PROFILE DESIGN All COSCO CONNECTOR SYSTEMS allow a lower profile tree assembly. The side entry system is specifically designed for applications where low tree profiles are critical, such as offshore applications. EXISTING WELLHEADS COSCO connectors can be installed in most existing WELLHEAD equipment to convert for use with submersible pumps or to replace other types of electric feed-through SYSTEMS . CANADIAN OILWELL SYSTEMS COMPANY LTD. 9760 60 Ave, Edmonton Alberta, Canada T6E 0C5 Tel: (780) 430-0840 Fax: (780) 430-0367 TOP ENTRY CONNECTOR SYSTEMS Top entry CONNECTOR SYSTEMS are used to convert existing wellheads for use with electrical submersible pumps or to replace existing electric feed-through SYSTEMS .

4 COSCO Universal tubing head adapters also use the top entry system . 90-DEGREE UPPER CONNECTOR LOWER CONNECTOR TUBING HANGER TWO PIECE 90-DEGREE TOP ENTRY ELEC-TRICAL system The two piece, top entry system is used where a tubing adapter (bonnet) is not required. It consists of: 1. A 90-degree upper CONNECTOR , and 2. A lower CONNECTOR The lower CONNECTOR bolts to the bottom of the tubing hanger and the upper CONNECTOR bolts to the top of the tubing hanger. The connection between the two connectors is made within the electrical connection port of the tubing hanger. In this configuration, the tubing hanger remains exposed in the top of the tubing head spool. To convert existing wellheads to the two piece, top entry system , it is required to change out the tubing hanger.
