BRIEF HISTORY OF BRITISH ENGINES LIMITED CMP Products is a division of British Engines Limited, a company registered in England, number 167542. British Engines Limited (BEL) was founded in St. Peters, Newcastle upon Tyne in 1922, when two brothers from Glasgow, Harold and Charles Lamb established the Company. Today the Company proudly remains in the same family ownership with Mr. Alex Lamb its present chairman, the grandson of one of the founders. The early British Engines Limited business was conducted from a building suitable for housing less than 12 employees, with marine engineering and...

CABLE GLAND AND CABLE CONNECTION SPECIALISTS INTRODUCTION TO CABLE GLANDS Cable Glands are mechanical cable entry devices, which can be constructed from metallic or non-metallic materials, and are used throughout all industries in conjunction with cable and wiring used in the electrical, instrumentation and automation systems. Cable Glands may be used on all types of electrical power, control, instrumentation, data and telecommunications cables. They are used as a sealing and terminating device to ensure that the characteristics of the enclosure which the cable enters can be maintained...

CABLE GLAND AND CABLE CONNECTION SPECIALISTS For information purposes, here is a summary of the 1 ) Material : Metallic, Non-metallic or a combination of both i) For Cables without Armour - ill) For Cables with Armour - Retention Class (A or B) 4) Resistance to External Influences These can be further explained as follows :- 1) Material : See Page 177 for CMP specification i) For Cables without Armour - Anchorage Category (A or B) The actual Performance Capability for the CMP metallic cable gland range intended for unarmoured cables far exceeds the requirements of EN 50262 :1999 Category B...

CABLE GLAND AND CABLE CONNECTION SPECIALISTS i¡¡) For Cables with Armour - Retention Class (A or B) The actual Performance Capability for the CMP metallic cable gland range intended for armoured cables far exceeds the requirements of EN 50262 :1999 Category A & B 3) Electrical Properties - Protective Connection to Earth (Category A, B or C). (See also the technical information detailed on pages 27 & 28.) Note: Category A, is the minimum requirement which may apply in cases where the cable armouring (other than steel wire) is the limiting factor & where the cable gland is screwed into a...

CABLE GLAND AND CABLE CONNECTION SPECIALISTS Category C, is the highest requirement, which may apply in cases where steel wire / metallic sheathed armoured cable is used and the system relies on a low sensitivity method of secondary protection against fault currents and where integral earth lugs (e.g. CMP CIEL) are incorporated into the cable gland, (see page 28 and 100 for further details). 4) Resistance to external influences - i) Ingress Protection Minimum of IP54, ii) Salt & sulphur laden In respect of 4) i. above CMP Products can confirm that its minimum Ingress Protection rating is IP...

CABLE GLAND AND CABLE CONNECTION SPECIALISTS CRUCIAL CABLE CARE When terminating cables and wires during the process of installation of electrical equipment this should be done by qualified and competent personnel in line with good engineering practice, observing safe electrical practices. It is also important that the correct cable entry device or cable gland is selected to suit the cable being used. For instances using normal unarmoured cables, the cable would usually be fed through a cable entry device that has a sealing ring activated onto the cable outer sheath. The choice of cable...

CABLE GLAND AND CABLE CONNECTION SPECIALISTS iv. Compensating Displacement Seal (CDS) System (Sealing Ring) The Compensating Displacement Seal system utilises the principal of the Displacement Seal but with the addition of a compensator that limits or controls the force applied to the cable inner bedding. v. Compound Barrier Seal (Epoxy Resin Compound) The compound barrier seal is made on site by the technician completing the installation and is used primarily in hazardous areas where the inner cable bedding must be removed and a hard setting resin barrier seal that has been specially...

CABLE GLAND AND CABLE CONNECTION SPECIALISTS Cable Gland Construction utilising Displacement Seal This type of seal is usually employed in a cable gland that utilises a 3 stage 'Step by Step' sequential make off, where the tightening of the armour termination is separated from the activation of the inner seal. This enables the effectiveness of the seal on the cable inner bedding to be tested before the armour is terminated. This means that unlike other designs the user is able to determine that the engagement of the seal on the cable inner bedding is not too light and not too heavy...
