Disclosed is an installation tool including a body (100), a holding head (300) and a power lever (200). The power lever (200) has a base end (200A) extending from the rear end of the body (100) and a top end (200B) extending from the front end of the body (100). The installation tool further comprises a hammering tool (500) adapted to hammer the base end (200A) of the power lever (200) to exert an impact force to the power lever (200). The top end (200B) of the power lever (200) pushes the first work piece (10) forward under the impact force to force the first work piece (10) to be inserted into the fitting hole of the second work piece (20). It is possible to manually hammer the power lever (200) by the hammering tool (500). The installation tool is simpler in structure, easier to operate and safer to use.

FLAT DROP CABLE WITH FEATURES FOR ENHANCING STRIPABILITY
A flat drop cable has notches or other structures for enhancing the stripability of the jacket from the a core of the flat drop cable. The notches can have an angled configuration with surfaces that converge as the notch extends into the jacket. Inner edges of the notches can be positioned along a tear path that intersects the core of the flat drop cable. For example, the notches can be offset from a minor axis of the flat drop cable a sufficient distance such that the notches are positioned outside a central boundary region that extends tangent to sides of the core and parallel to the minor axis of the flat drop cable.
A lightning arrester comprises a housing; a mainbody partially mounted in the housing; an encapsulation cap mounted at a first end of the housing; and an elastic apparatus compressed between the encapsulation cap and the mainbody. In the lightning arrester, the encapsulation cap comprises a circular base mounted at the first end of the housing and a mounting portion formed at a substantial center of the base. A first end of the elastic apparatus is mounted in the mounting portion, and a second thereof is abutted against the mainbody. In the lightning arrester, a reliable electrical connection may be arrived. By the pressure relief apparatus, electronic devices and accessories of the lightning arrester may be prevented from being damaged by escaped substance generated during the lightning arrester exploding.
