Deep Well                                 3,500 - 4,400

 

Note:    For cables that are not new, the breaking strain will be lower than the quoted values. Thus 50% of the new cable     breaking load is the maximum that may be pulled without consulting the Base.

Dear Sir,

Kindly quote for us Standard 7/32" mono conductor logging cable quantity 6000Metres as per the attached document/specif ications on page 32.

Kind Regards,
Harrison
