  • Patent number: 6588714
    Abstract: A safety valve incorporated in a tubing string has a diameter considerably larger than that of the rest of the tubing string. A cable protector is fastened onto the tubing string at the lead in to the safety valve to ensure that cables extending along the outside of the tubing string are able to cope with the changes in diameter without strain or damage. The cable protector is formed from two cast bodies and hingedly connected together to define a substantially circular inner cross-section. The upper body member is provided with an elongate cable slot in which the cable is received. In addition, the upper body member is shaped to give the cable protector an increasing internal cross-sectional size, or transverse dimension, along its length from one end to the other and, whereby the distance of the cable from the longitudinal axis of the tubing string increases as it extends therealong. Thus the cable received within the cable slot is guided along a path which has a varying spacing from the longitudinal axis.

  • Publication number: 20020030144
    Abstract: A safety valve (4) incorporated in a tubing string (2) has a diameter considerably larger than that of the rest of the tubing string (2). A cable protector (10) is fastened onto the tubing string (2) at the lead in to the safety valve (4) to ensure that cables (8) extending along the outside of the tubing string are able to cope with the changes in diameter without strain or damage. The cable protector (10) is formed from two cast bodies (12) and (14) hingedly connected together to define a substantially circular inner cross-section. The upper body member (12) is provided with an elongate cable slot (26) in which the cable (8) is received. In addition, the upper body member (12) is shaped to give the cable protector an increasing internal cross-sectional size, or transverse dimension, along its length from one end (B) to the other and (B′), whereby the distance of the cable (8) from the longitudinal axis (X-X) of the tubing string (2) increases as it extends therealong.
