3 1 Copper Connector of C-Type (Copper C Tap) It is generally called as 'Copper C Tap' or 'Copper C Crimp'. It is a grounding sleeve that connects grounded electric cables without high tension. We are manufacturing two types of connectors. One is for general customers in domestic market with KEPCO standard and the other is for MOLEX. Best quality and price made us acquire good reputation from our customers. KEPCO Standards Domestic Market The chamfering on edges protect cables from scratch and being cu during compression.

4 2 Copper Connector of E-Type (Copper Branch Connector) These useful connectors have the same outer size for all types, which enables easy work without changing crimping dies. It does same function as H-Tap, used to connect main copper cable and branch one for low voltage. a. Connection by binds b. Connection by connector Connection by connector is much better than that by binds in lower cost and higher quality. Same outer size for all types Reduce installation time Example of wire insertion into connector Page 4

5 3 Aluminum Connector Aluminum connector, made of primary high-grade aluminum, connects ACSR wires for high voltage, which prevents electric accidents by firm connection. Inner holes of connector are plastered with the compound that helps to eliminate gap between wire and connector.

6 4 Copper Busbar With advantages of excellent conductivity, easy formation and easy treatment, busbar is used for interconnection of electric power system. Busbar reduces system costs Busbar reduces manufacturing costs by decreasing assembly time. Busbar improves reliability Busbar can help you to lower wiring errors, which results in fewer reworks, lower service costs. Busbar increases capacitance Increased capacitance results in decreased characteristic impedance. Busbar provides denser packaging Busbar needs smaller space, which helps to decrease total system size and cost. Busbar improves thermal characteristics As a wide & thin conductor, busbar secure better airflow in systems. Generally, to make smaller package, the cost for radiating heat from systems has greatly increased. Busbar not only reduces the system size but also improves airflow with its sleek design. Page 6
