Introduction and purpose:

The 24kV/250A elbow cable connector is suitable for the inlet and outlet terminals of ring network switchgear cabinet, cable branch box and box-type substation, with rated voltage of 24kV and rated current of 250A cable section of 35-150mm2.
Section marks are marked at the end of the 24kV/250A elbow cable joint. Please check whether it is consistent with the cable section before installation.
The product is made of epdm rubber, non-toxic and tasteless. The lower cone structure has the effect of uniform electric field, which can effectively eliminate the distortion electric field at the cut off place of the cable terminal.

Preparation before installation:

1. Cable shall be divided into corresponding other installation process (cable exploitation treatment or cold shrinkage process)
2. Single-phase cable handling: remove the copper shielding layer 170mm from the top of the cable, remove the semi-conductive layer 145mm from the top, and remove the exposed long-core conductor from the insulation layer 50mm from the top.
3, clean the insulation surface of the core, ensure that clean, smooth, no dents, the core insulation and semi-conductive layer transition place to be smooth and round, no steps or sharp corners.It is necessary to make a 3mm long cone at the transition of semi-conductive and core insulation, and then pour a 3X45℃ chamfering Angle at the insulation end of the core.
4, clean the cable and press and connect the knuckle type terminal: note: the screw hole direction of the knuckle type terminal should be the same as the direction of the insulation sleeve hole, then press and connect, after pressing and connect, remove the burr caused by pressing and connect.Clean the cable core insulation from top to bottom with clean paper. Do not bring conductive particles or other conductive materials to the insulation layer.

installation procedures and notes:

1. Use the cleaning paper to clean the corresponding matching parts of the elbow cable connector and evenly smear the silicon grease, then push the cleaned cable into the vertical hole of the elbow cable connector.Visual inspection shows that the screw hole of the compression terminal is aligned with the body from the large end of the elbow cable joint, and the cable is installed in place with the elbow cable joint.
2. Align the hole center of the elbow type cable joint with the end of the straight body conducting rod, rotate clockwise, connect the straight body conducting rod with the elbow type pressing terminal, then insert the special hexagon wire into the hole on the back of the straight body conducting rod and tighten it firmly.
3. At the bottom of the elbow cable joint, wrap the semi-conductive belt and overlap with the outer shield layer of the cable.
4. Push the assembled elbow-type cable joint into the bushing seat, and ensure full contact between the straight body conductive rod and the conductor in the bushing seat. Then install a fixing plate on the back end of the elbow-type cable joint to prevent loosing and damage to the equipment.
5. Install other two-phase cables and fix the cables in the same way.Connect the grounding wire on the elbow cable connector to the fixed grounding copper bar of the equipment. It should be firm and reliable, play the role of grounding and make the phase color mark finally.
6. If a live indicator is needed, remove the cap of the test point and install the live indicator at the test point.

Installation, repair and disassembly must be carried out in the state of power failure!
Warning: please be sure to follow the installation instructions, if the installation is not correct will lead to normal use, serious will cause damage to personnel or equipment!
