Application
* Connect single-phase or three-phase insulated cables to transformers, switchgears, branch boxes and other equipment through 630A prefabricated connectors.
* Suitable for indoor and outdoor installation.
* Rated voltage: 8.7/15kV, 18/24kV
* Continuous rated current 630A; (900A overload can last for 8 hours)
* Extendable (JBK) rear connector or (HBLQ) series surge arrester to achieve multi-channel installation or provide overvoltage protection.
* Cable characteristics:
-Copper or aluminum conductor
-Has semi-conductive or metal shield
-Cable conductor cross section: 12kV 25-500mm2, 24kV 25-500mm2
Type Description
Feature
* When mated with a suitable bushing or plug, it provides a fully shielded and fully sealed detachable connection;
* Can be operated under water and other harsh conditions for a long time;
* The built-in capacitance test point is used to determine the charged state of the circuit, and must be used in conjunction with the charged display;
* No requirements for minimum safety distance between phases;
* The installation can be vertical, horizontal or any angle
Product Structure
1. Double-headed bolts: Metal bolts ensure that the conductor and the bushing are tightly matched.
2. Insulation layer: unique formula and mixing technology ensure the high quality of prefabricated insulating silicone rubber.
3. Insulator: The epoxy resin insulator contains threaded metal parts to ensure a close fit with the stud bolts.
4. Inner semiconducting layer: Prefabricated conductive silicone rubber effectively controls electrical stress.
5. Stress cone: Stress cones of different sizes are used with cable joints to ensure water sealing and cable stress relief.
6. Grounding eye: pre-injected into the outer shield for the connection of the grounding wire.
7. Outer semiconducting layer: The prefabricated conductive rubber overlaps with the cable shielding layer to make the shielding continuous and ensure that the outer semiconducting layer is grounded.
8. Crimping terminal: All-copper or copper-aluminum crimping terminal is suitable for copper or aluminum conductor.
Installation
* No special tools, straps or padding required;
* The cable connector is energized and operated immediately after being installed to the relevant parts;
* Provide regular assembly parts and installation manual.
