End raychem coupling design
Design and mounting of the end raychem coupling of outside installation it is similar to the previous description for internal installation. Additional trekingostoyky insulating skirts take seat on veins (quantity see the table).
The armature for solderless grounding is ordered separately. Set of the end raychem coupling with modification of L12 modification of L16 under M16 bolt includes cable bolt terminals with opening under bolt of M12 and, respectively.

Note: Length of veins can be determined by the place of mounting. The minimum length of veins is 320 mm for Uo/U = 6/10 kV, 460 mm for Uo/U = 12/20 kV and 800 mm for Uo/U = 20/35 kV. For end couplings with bolt tips under bolt of M16 to use modification of L16. The armature for solderless ground connection is ordered separately.
