  • Section insulating device and use of same
    Patent number: 10988050
    Abstract: A section disconnect device for a contact line assigned in particular to railborne vehicles as overhead line and carrying high voltage, having a single section arrangement (10) with multiple line sections extending, such that it is tensioned or can be tensioned, between two contact-wire connecting heads (12, 14) and provided with insulator means (36, 38), which line section arrangement is constructed such that it can be mounted by means of respective accommodating sections (66) of the contact-wire connecting heads in an electrically and mechanically contacting manner between exposed ends (16, 18) of the contact line, as a result of which at least one of the contact-wire connecting heads (12, 14) has adjustable level equalization means (66, 68, 70) for interacting with a head-side end (20, 24) of the line section arrangement (10), which are constructed in such a manner that, with respect to a current collector contact, in particular a current-collector-contact side of the contact line and/or a current-collecto
